I actually have both and both are on OOB condition. I find the Cell handles a little bit more oil. On the Scorpion pattern, the Cell would make it to the pocket, while the Resurgence was leaving 2's, 2-8's, 2-8-10's from the same spot. Also, I think the Cell gives me a little bit more mistake room. Both are very good balls. I use my Resugence as my step down if the Cell start to hook too much or begins leaving a lot of 9 pins.
I have a Rival as well and am thinking of getting another Cell, shining it up to fit between the Resurgence and the Rival, so my most hooking ball down would look like Cell-OOB, Resurgence-OOB, Cell-Shined, Rival-Shined.
