Which clutch is best, Borg and Beck or diaphragm?

I'm running a McLeod Super Street Pro... It's a Diaphragm, the disc is half Organic & half ceramic... I was concerned about the ceramic being "grabby" but it's actually very smooth if driven normal but if you dump it there's no slipping, it bites & launches.... Rated at 500 ft/lbs of torque my little 340 will never hurt it....

The pedal is light, nothing like the B&B in my old Hemi Challenger.. I haven't tried shifting it past 6400 so I can't say it won't stick the pedal to the floor like OE clutches in GM products were known to do in the 60's.... But I suspect the technology has improved in the fifty years since then....
