Gomoee go heliboard and don't ever look back.
I normally just go with gboard without internet permission, which I disable after initial install, because it needs to downloaded the dictionaries for my language.
But have been giving Heliboard a serious try. Predictions aren't as good as in gboard, even with Google's swipe library installed, but it's the closest I found. Both for English and my native language.
Give it a try.
Cheers,
