I do find FUTO is sometimes too aggressive about its autocorrection. Especially when trying to type into an email field or use an abbreviation or a hyphenated word.
I can't tell if swiping has gotten easier over time or not. Sometimes I can miss and it still knows the word, and other times it's simply impossible to get the word I want.
It feels as if the sentence context isn't influencing the choice of correction enough so I have to help it more than gboard. But overall I find it easier to use than the other open source / private keyboards I've tried. And thankfully haven't regressed to gboard since using it
