What tools do you use to make maps for your table?

I've tried looking and I have found a few decent generators, but I'm really looking for a making tool I already have a general layout in my head of what the city/region/continent but I can't draw for shit, and I want to find a tool that makes this easy? Makes it look nice, makes it easy to add points of interest and features, etc.

What do you use?

Edit: for clarification, this is for city/region maps, not battlemaps.

@Deimos clued me in to this site which lets you filter your Steam library using tags. I had no idea this was even a thing, and it made me want to know what else I'm missing. What are some great sites/tools out there that improve your Steam experience?

It should go without saying that they need to be safe to use. I know scam Steam sites are a dime a dozen, so make sure you're posting something that's properly vetted.
