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.

There's a popular trend on Reddit at the moment that they're struggling to engage with. The idea is that someone will post the question

"Ask me anything about my world"

And this does two things. It gives them an opportunity to show off their setting, and more importantly it gives them a prompt. Someone may ask a question you don't have an answer to, so you're supposed to come up with one. Doing this enough will help you flesh out your world in ways you may not have considered on your own.

I think the reason this is failing on Reddit is because there are a dozen people jumping on the bandwagon and filling the RPG subs with spam, which is causing other members to lash out at them out of fatigue.

I think we here on Tildes could probably handle it a little better, and it would be better served as a single thread. Top level comments are for asking questions, and then anyone is welcome to reply to those with their answers. By sharing the same pool of questions this will allow us to compare and contrast our worlds with our friends here and maybe help spur on the creative juices.

I'm starting a new campaign soon and I plan to create a homebrew setting and story like I've done in the past. I've used a combination of Google Docs, Evernote, and other general purpose tools for other settings and campaigns. Does anyone use something like World Anvil or Legend Keeper? Something else?

I'm still in the brainstorming stage of world building, and I'd like a place to collect my thoughts and plans. Ideally I'd be able to easily convert that into something searchable and updateable when it's time to actually play in the setting.

Do you use a single tool for creating maps, NPCs, plot points, history, and adventures? Or do you have a suite of tools you find works well to cover all those aspects?

For example, Guards! Guards! by Terry Pratchett has forever changed how I roleplay dragons.

I'm going on a camping trip soon. I've loaded up my eReader with books from Appendix N and am looking for other grist for the mill. Mainly looking for books at the moment, but feel free to suggest other things.
