What keyboard are you using?

Had the X9 Pro for 3 months and I'm sure the GBoard keyboard I'm using is getting more inaccurate by the day. It was great when I first got the ohone.. I've tried SwiftKey but it keeps changing layouts without me asking (changing the Returns key to an emoji key in certain apps etc) and I find it's autocorrect even worse than Gboard.

I'm after a keyboard where I can change things like spacebar length and individual key sizes, with decent suggestions.

Anyone found a good keyboard, or recommend layout, size and settings for the default one?
