I have 10spd Red on my BMC - braking is pretty spongy, shifts down the block are nice, shifts up are not, front ring shifting is OK. Levers feel OK, but the Rival shifters my GF has feel horrible and so cheap. I would probably take 5700 and definitely 6700 over that.
I honestly think that SRAM isn't all that.
