I also used it extensively. There are options to make the center spot much smaller that make it far easier to type with.

Also, my major complaint (and the reason I use Swiftkey now) is simply that the built in dictionary is simply not good enough at predicting N-gram sentences that I use often. There are times on swiftkey where I just tap the middle suggestion to write a sentence (although perhaps that's more revealing about my low-entropy text messaging habits than anything)
