I love Swype. I've used it on every phone I've had. Only complaint is getting smiley faces instead of an " I" when I Swype too fast.
I've switched back over to Swype because it's so natural for me after using it, cumulatively, about 3 years. The only thing that's almost pulling me back to Swiftkey is the arrows. I used the crap out of those arrows. I hate if I need to change one letter or something having to perfectly align the little draggy thingy or just start the word over, when I could've just tapped the back arrow twice for a quick change.
But I can send a 99% accurate text without even looking at the phone, so....a fair tradeoff.
