To add my anecdote, I'm on my third season with about 15K miles on a Giant TCR with a BB86 and zero issues. In talking to mechanics I ride with, BB86 is generally less problematic than Trek's BB90, Cannondale's BB30a and Specialized's OSBB (which is essentially BB30). In my experience of riding with lots of people, that's also what I've seen anecdotally with Treks being probably the worst.
BTW, I know many, many people who own a Specialized Fatboy and every single one of them has had issues with the BB. This is probably because fat bikes are generally ridden in awful conditions, but I also think Specialized really cheaped out on making the shells for those bikes.
