The biggest difference, or what should be the center of attention is modability. The 7AT will do fine with bolt ons, some will argue it will hold a SC with low torque figures with mild upgrades (tune for line pressure, trans cooler and maybe even
VB upgrade) but the 6MT will always be best for high power applications and modability. Lightweight flywheel, different clutch, no need to cool the fluid, etc... Biggest disadvantage is the CSC/CMC.
