Keyboards Tried:
Stock (Touch Input)
MotoX
Swype
SwiftKey
My Default:
MotoX
As a two handed texter, portrait or landscape, Swype wasn't a solid fit for me. Now I am not saying that it isn't an exception keyboard because it really really is. The MotoX multi-touch keyboard just fit my needs better and allowed me to type faster 2 handed than Swype would allow 1 handed.
However, I am trying SwiftKey and I like it a lot. Same excellent touch response as the MotoX (with the awesome addition of vibrating feedback). I'd like a mic button and a few other little things but I am going to give it a week and see what its 'learning' abilities really are.
I want to say this though, the vibration I thought would be a deal breaker on the X keyboard and it ended up being too good of a keyboard for that to happen. I am hoping the lack of mic and others, double space to period function can be overcome by its awesomeness.
