I’ve only really used AnysoftKeyboard and Heliboard myself. But my mobile keyboard ‘needs’ are really low - mostly some specifics around terminal keys and multi-language.
Honestly, if your setup works for you maybe don’t rush into changing right now. Don’t let perfect be the enemy of good and so on. When you have the time and motivation you can always take some time to investigate the other options more in-depth! Sorry I can’t be of more help here


Oh yes, I cannot vouch for anything on the playstore since I use f-droid for most of the apps on my android. Just makes more sense to me, FOSS platform for FOSS apps.
I do know that AnysoftKeyboard has a bunch of Dvorak layouts since that’s the one I use (the kb not the layout 😅) and so could quickly check.
But regardless, if you are happy with the current keyboard functions I don’t mean to harp on about these others - and I think cutting off outbound traffic for the futo is a clever step!
