If you're looking for WMO shape, the general choices are Zowie AM, Steelseries Sensei, Steelseries Kana and Roccat Savu.
I have a Kana and I'm very happy with it since the firmware updates since it was released, and since putting proper teflon feet on it. I've read that the newer ones ship with proper teflon feet so that isn't an issue anymore. It does have mild prediction. In my personal opinion the prediction is very slight. I do not notice the prediction in day to day usage or gaming, I have to look for it specifically. I do not have any tracking issues on my two QCK pads (one black one colored) or on my 9HD hardpad. If you buy a Kana, keep in mind that the white one is glossy if you like/dislike that.
