I haven't even tried the default keyboard on 2.2 since I've been using SwiftKey. Is the new one really that good? I haven't tried the droid x one either but I've gone through shapewriter, old stock keyboard, and swype.
Default is much better now but Droid X keyboard is still my favorite. SwiftKey was a pain in the arse in my opinion and got uninstalled after using it for just a few texts. Swype is good on 2.2 but I really want the Droid X keyboard back bad!!
