I am a bike mechanic although I don't work as such in a retail shop. I do my own work and will work on others bikes at times if they ask me. I would not have a press fit BB if I could get a threaded. Press fits can work but they normally require more work and have more trouble. The threaded is not broke and it changed just because it was easier to do a frame for press fit than threaded. All my bikes of the past 10 years I never once had an issue with the BB. That is probably 50000 miles and they work fine. I am partial to shimano because I believe they have the best front crank performance over the rest. I admit that I don't know Campy but Camp is great stuff I just don't want to buy more tools.
I have road Treks BB90 and they don't seem any stiffer or better than threaded, although they are nice bikes. I hope specialized will return to thread because they I could at least look at one of their bikes. These days though I find Ti to be the best and they are usually thread BB.
