I chose vlemmy.net for the exact same reason, too. Also it was the top instance on https://join-lemmy.org/instances the day I wanted to join another instance (I was on lemmy.ml then).

You would probably get used to FlorisBoard after a bit of time if you try it. I was used to SwiftKey but I didn’t like it because it doesn’t have a good history, like suggesting private email addresses to other users, and it’s for Microsoft. But now I’m typing this using FlorisBoard.

Definitely FlorisBoard. I’ve also tried AnySoftKeyboard and some others in the past, and I think FlorisBoard is the best.
