I use an old version of the Swype keyboard, that came pre-installed on my Galaxy S6. Unfortunately, I've become so used to swipe and gesture support (particularly "Ctrl"-{a,x,c,v}) that I'm waiting on a FLO keyboard that can do those things to switch.

I haven't seen Multiling O Keyboard (https://play.google.com/store/apps/details?id=kl.ime.oh) mentioned yet. It's not nearly as accurate as Gboard out of the box but once you get used to it and train it well it's not bad. It is insanely configurable.
