The grudge would definitely have better pop, just due to regular camber. It all comes down to what you want to ride. I ride park a lot and mainly hit the jump lines, I can't stand rocker when hitting jumps. But I have friends that hit the biggest jumps at our mountain on their rocker boards and they like how the board feels. It's all preference, do you have any previous experience riding rocker boards? If not I would give rocker boards a quick try before you buy one.
