Original switch release or hd 2d?

So I have the original switch releases of I, II, and III that are based on the mobile ports. I beat one already a year or two ago and had a decent time. My question is should I play II and III as I have them or get the hd 2d remake.

I know it seems like the hd 2d remake is the obvious choice but I have some caveats. I'm a stay at home caretaker of a family member. Currently unemployed (though I'm trying to get caretaking for them as a job) so I'd have to wait and only get one of the releases as a Christmas gift and the other as a birthday gift next summer should employment not come through by then.

I know the remakes of I and III aren't out yet but based on your impressions and what III hd 2d is like.

So I'm wondering if it's worth waiting and sacrificing other potential games when I have two playable versions now.

Thoughts?

I played the older 2017 demo with 2 characters and really liked the gameplay and visuals. Great old-school feel, yet very polished to feel somehow modern and unique, with novel mechanics like the character-specific skills or "paths" when interacting with NPCs.

I also tried the new June 2018 demo for a few minutes as Tressa. It was fun but jarring with few interactable NPCs and very little in the way of introductory story or cutscenes, fewer than I remembered from the old demo. I wasn't sure if this was because it was still just another demo, so I've decided to hold off and start from scratch in the full game. (The save file carries over from the June demo to the full game.)

I would normally have preordered, except for my extended backlog from the Steam summer sale.
