I was surprised to experience this when putting the 10 speed bike in service. At any rate, I'm a believer.
Interesting. My crank, a Campy Record square taper, is nice and I don't get any chain rub. Not a bit. If I were outfittng the bike today, sure, I'd be most likely with an intergrated set up, new Campy or FSA, or what ever. Until something breaks or wears out, I can't come up with any good reason to abandon square taper.
