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.
The 105 could be a square taper or Octalink.
