I installed MessageEase and while it's indeed easier to pick up than 8Pen, it's only just as fast, because it requires both taps and swipes. Meaning, that you need to lift your finger all too often, and then switching from one mode to another, and that takes time. Overall, I'd say that 8Pen is better in smaller screens than MessageEase, and could easily support blind-typing, something that's not as easy on Message Ease. On the plus side, MessageEase is simply easier to learn.
