So far most of the comments are anecdotal, whether from real experience or "heard about it". That's not to be unexpected though. This is exactly the kind of discussion that the bike companies want their customers to have; it creates brand loyalties. It's quite obvious some of us have drunk the various Kool-Aid of said company.

For me, at least for now, I'm brand-agnostic. Admittedly - call it vanity or narcisstic tendencies - coolness and rarity are a couple of the features that's important to me, regardless of brand.
