I currently use the Gaomon s620, and it's worked well so far, but I don't know if it's a tablet I'll use forever. It would be great to have a tablet with no hardware smoothing, although the smoothing on the s620 is hardly noticeable as is. Lifeline switched from the s620 to the 472 a few months ago and was very impressed with it, and I trust his judgement as a top 10 player. However, I'm not sure how much better the 472 is or if it's worth spending extra money while I already have a decent tablet. To people who have played with both tablets, or own either of them, is the CTL 472 worth it in my situation?
