Shim or camp?

Can someone give me some input as to the quality of Campy Mirage vs. Ultegra or 105's?

Thanks

 

I'd make the comparison veloce vs 105 and flip a coin. I lean toward Veloce just because I like the campy sifter/brake lever layout better.

 

i like to think that 105 is somewhere in between centaur and veloce, it may or may not be the case.

 

Does it REALLY matter? I also think there is no abslute direct comparison,but ya gotta start somewhere.
