Ask HN: Experience Using GitHub Projects?

We're currently using Trello for our team. We like the simplicity a lot, and we keep things straightforward: one board, a handful of columns, barely use labels.

We're working with GitHub automations more and more, and have migrated our docs and discussions there. So we're considering moving to GitHub Projects too.

At face value, it's looking pretty barebones: the UI is clunkier, it seems to force a topology on the board setup. I also haven't found a good mobile app for it.

Do you (or have you) use GitHub Projects? What's your experience like? Any tips on how to use it well in parallel with the rest of our setup?
