It all depends on what strategy you are going to go for of course, but if you are going to play any defense or fight for balls in the neutral zone, I highly recommend tank over mecanum. 99% of the time, you will get tossed around like a rag doll when facing non-mecanum robots. No traction. But as one user suggested earlier, if you are very familiar with mecanum and not familiar at all with tank, or your driver is skilled enough to handle the challenges of mecanums in this game, then go with mecanum. Otherwise, I say tank.
