I can't comment knowledgeably. I just regularly have to try over and over again to get it to produce the word I want, and my memory is that this happened rarely on Android.
Wait! I do have a specific criticism!
There are certain two-word sequences it will not produce ("kill myself", "white women") and I could do without that little bit of editorial oversight thank you very much.
And expletives. If I want to say fuck, that's my business, I don't need my phone refusing to allow it. If not for how embedded I am right now in the ecosystem, this keyboard & vocabulary behavior they force on me might be enough to make me switch.
Yep, there's a whole set of censored phrases. Kill won't let you type a lot of things after it, including "him" and "her" (well, I haven't tested on iOS 27 yet). I haven't tried the white woman one though, that is cracking me up.
update: Okay I tried and sure enough, I'm laughing even harder now. The closest I could get it to swipe was "womanhood". Lots of Wohan's though.
