I am sure people will disagree, but Campagnolo is light years ahead of Shimano for brifters. I don't know much (or anything) about bar cons...since I hate them...but the ergos are a far superior product to the STI stuff...better front trim, more precise shifts, less maitenance and more durable. I will never build up a newer bike with Shimano again...Campy is worth the price difference.
Please note...I;ve never ridden the electric stuff, so I could be totally oput dated by saying that.
