I haven't used the stock Android keyboard since Gingerbread. It really wasn't that great. I tried the stock ICS keyboard and yes it is better but Swiftkey is awesome. It's predictions are second to none. There are many times where it completes entire sentences for me. I have fat thumbs so the larger screen on my Nexus S definitely helps. Plus all you have to do is swipe right to left and it'll delete word, swype down to close the keyboard, quick and easy. You can even choose themes, add arrow keys if you want, and choose the typing style you prefer. It's seriously awesome.
