Both of those are great components and I've heard people using Campy's for years. If you're worried about durability with the SRAM, then I'd consider using Force. The latest Force is virtually indistinguishable from Red and has some steel hardware instead of titanium that might make it more durable (for instance, the front derailleur). Only penalty is a little bit of weight.

Also, instead of just their appearances, consider other things as well. Some people don't like the thumb shifters of Campy, while others won't use anything but. SRAM uses a very intuitive "double-tap" system but is a bit noisier in terms of drivetrain.
