Using GBoard begrudgingly because there’s no better alternative for me personally. I depend on the swipe typing and gestures a lot. Personalisation is off, and I don’t use the next-word suggestions that often.
I don’t really like SwiftKey’s design or its Microsoft affiliation. I wish there was a good open-source alternative. Florisboard looks promising, but the last time I tried it, it was still lacking in features.
Aside from the ads, you also have to sift through all of the crappy clones and shovelware to actually find something useful.
This was my exact experience a couple of days ago when I was trying to find a CSV viewer.
