Erm.. No.. I have both.. My one complaint with the SRAM chain is if you break it open you need a PowerLock (Not Link) to put it back together and so far Ive yet to come across a shop that stocked the PowerLocks.

What I did on my last build, since I needed a chain and didnt have a PowerLock was put an Ultegra chain on it with a Connex link.

The SRAM cassette is missing some teeth that's supposed to help with the shifting. I cant tell much difference between it and a Shimano tho.
