Seems like this is a new swipe model, though, so it should be more comparable. I also had to switch back to GBoard on GrapheneOS since I was spending more time fixing typos than actually typing with FUTO but I'm willing to give it another shot.

I agree. I find that swipe typing on Gboard feels much better than FUTO's because I think it adapts to my typing style. I tried FUTO about six months ago, and it was a bit frustrating so I switched back to Gboard. Hopefully, it has improved since then, but I haven't checked.
The early iterations of swipe were very inaccurate, yes. But the newest swipe release mentioned here is much more mature.
It's not perfect, but it's practically on par with GBoard aside from a few blips here and there. It's enough for me to get rid of GBoard for good, and not consider reinstalling it.
I run GOS and have tried it, you spend more time deleting works than actually using it.
I was forced to install Google GBoard instead and revoke its network access. Gboard swipe typing works flawlessly, FUTO still an Alpha project.
