I guess this is just a thing I like to do lol. I got an OLED Steam Deck and have been playing around with it for about a week, so I wanted to share what all I got.

TL;DR: OLED is the definitive version of this product. If you're at all interested, whether or not budget is a concern this model is worth looking at, especially if you can actually get your hands on one to try for a bit. Words aren't quite what they need to be to get across how it looks and feels.

The long of it:

Valve wasn't kidding about stuff like a little performance improvement and better battery life. It feels like someone took the LCD deck and made a checklist of every single thing that could be improved, and then did it. The result is just about the best refresh of a product I've ever seen.

The screen is the most obvious upgrade and it really is great to look at. It is a big jump to go from an LCD at 60hz, to OLED at 90hz with HDR available. As great as VibrantDeck is, no amount of color fuckery can really reproduce what is happening when you have these features. For games that support HDR, it can feel like you've actually made an upgrade, because of how differently it can handle things like bright flashes of light and particle effects on top of the color differences. The refresh rate is tied to the frame limiter by default, so when you drop the frame limit the refresh rate tends to stay double whatever that is. 40fps/80hz feels better than 40/40 to me, like stuttering just isn't as bothersome.

Be aware it's on developers to implement HDR, which means sometimes you run into a game with a shitty implementation. FFVII R comes to mind. Just know that if you run across a game where this feature seems to make the game look terrible, it's not the device doing it.

The improvements to the battery do mean something like a ~40% increase. Games like Armored Core VI and Elden Ring tended to last about 1.5-2 hours on the LCD model, on OLED it's more like 2.5-3, and this is the sweet spot imo. Rare that I'm gonna sit down and play for that long in the first place, so having this much power available means being able to play here and there with much less concern. Games that already played well in a low power state just get that much more time. One thing to know if you're coming from an LCD - it doesn't save your power profiles. Input profiles yes (if you saved them), but power settings need to be redone game-to-game.

The device itself is a little lighter, and it feels like it sits in my hands a little better. The difference is minute, but noticeable, and nice. All of the buttons feel good, the sticks have slightly more resistance to them, and the trackpads are much nicer to use. In particular, the way you click the trackpads is more forgiving by default, so while it is a little easier to mis-click it feels more like using a "real" trackpad. The deck in general is the only device I find doesn't really aggravate my carpal tunnel, and the OLED model keeps that up.

On the software side there isn't really a difference - SteamOS is more or less exactly the same with a few OLED-specific settings. Most of your info gets saved and loaded up when you log in. Cloud saves are one piece of course, but too, any controller profiles you saved will come back, and the SD card can just be freely transferred/there isn't really any setup to it. From boot to play I mostly just waited on the game to download - setting up the device was as simple as waiting for it to do an update, then log in, and that's it. It doesn't pester you to register for anything/no ads.

Things like sleep/wake and transitioning to desktop mode are faster and more consistent. Pretty regularly, my LCD model would fail to sleep/wake correctly - I'd put it to sleep and upon waking it, it would reboot. Inconsistent but often enough to get annoyed with. With the OLED model, i notice this doesn't happen as often. It still does, but much less frequently. The improvements to the trackpads means I use desktop mode more often, it feels much nicer to navigate. All of the stuff I had before was simple to install and restore - emudeck, decky, cryoutilities all installed without any issues and worked fine after I moved over all my stuff from the first deck. Haven't hit any issues with decky plugins either.

Even the carrying case got a pass. It's been redesigned a little, with an extra velcro fastener bit and tighter mold inside, black instead of white.

Transferring my information was about as easy as you could do. There are several options - I mostly used KDE connect, but there's also Warpinator, and a deck plugin called DeckMTP that can let you do a direct USB connection. Literally just copy/paste, once I installed all the stuff I had before I could just drop in the old device's things and be good to go. One thing to be aware of, is that for games which don't support Steam Cloud, you need to copy their save data over. That's gonna mostly be in a folder in /steamapps called CompatData. Takes a little doing but it's not hard to figure out. The hardest thing to set up was STALKER Anomaly, and all that was was about a five step process of clicking things in Wine. By the way, if you make a custom controller profile for a non-steam game, when you add that game to the library make sure it has the same name as before and your controller profile will be saved!

Overall I'm impressed to the point I intend to hold off buying any more PC hardware until a Deck 2 appears. If that product gets the same kind of attention this one did there's no doubt in my mind it will be fantastic. Considering too, the ability to dock and use peripherals, I think I'd feel safe recommending an OLED steam deck as a replacement for a gaming machine + non-work computer to just about anybody. $399 as a base price for PC Gaming is fucking awesome, and $549 for this improved model, at least I feel is very much worth it. $150 for an OLED screen, more storage, bigger battery is not bad. The deck is a hugely popular product, which means you get the added benefit of folks constantly tinkering and messing with stuff to make it work, on top of the odd developer specifically targeting it (such as in Cyberpunk, or how Bannerlord reworked its control scheme). Those kinds of communities exist around other devices, but not nearly to the same extent, and they'll die fast as those products come and go.

So that's what I got. I hope this was informative and helpful. If you have any questions I'm happy to answer as best I can. I'm super happy with the deck as a product, it feels a lot like getting to see what it looks like when someone goes the distance and throws their full weight behind this kind of product.

Edit: I don't know how well this will come through looking on different screens, but here are a few screenshots from AC VI and Morrowind that made use of HDR. Even if it doesn't come through - if you've never owned a deck and were considering one, yeah stuff can look this good on it! It's amazing.
