Comes down to personal preference. You can bomb every bit as fast on a CRC board as you can a pure camber board they just feel a lot different. CRC will have a looser, more skatey feel to it while camber will feel more locked in. Neither is necessarily better, just different. IMO, everything camber can do RCR can do better. Has all the edge hold of camber with none of the catchiness. If you have liked camber in the past and want a similar feel, go RCR.
By the way, CRC = camber outside of the inserts with rocker between the feet while RCR = rocker outside of the inserts and camber between the feet.
