The 105 is square taper?
I don't know how they are going to play out in the future but EVERYBODY has switched to external bearing bottom brackets, including Campy which is usually very conservative. I expect there are no major or inherent weaknesses or the word would have certainly gotten out by now.
I've had both and think as far as quality, they are very similar. But, all things being equal, the Shimano would probably be what I would think is better simply because of the availability. I would think the Bontrager is much more limited in who has access to it.
