I've tried Fleksy and Swiftkey. Fleksy was beautiful but it was not for me. Too many awkward gestures if I remember well. I used Swiftkey as my main keyboard for a while because of the ability to have 3 languages simultaneously and the amazing predictions. I switched back to GK because of aesthetics and feel. Also, swiping is much better but predictions are not as good. I've been teaching it french and Spanish by adding to my personal dictionary for maybe a year now so I think I'll stick with it from now on. I wish Google could get their hands on that Swiftkey prediction engine though
Would you use any app instead Google keyboard? - Google Keyboard
