Which clutch is best, Borg and Beck or diaphragm?

I would have the one that you have rebuilt. We have a local shop here in Lincoln that rebuilds them.
The Clutches available on Brewers Site for Slantys and 273's are $800 dollar Diaphragms!
So, when I need a Replacement... Should I just take my old modified B&B and have it Rebuilt?
It's the 10" Version w/ the Special Scalloped Bolts that replaces the old 9 1/2" one.
(can't find them Anywhere now!)
