As for the bike - I'd mirror everyone else here - go for the one with the best fit and feel.
Ha, isn't that usually how it works? Long-time serious amateur (like from back in film developing and printing days). Still shooting my 5D (but eyeing the 5DIII at this point). Have my brother's old film Nikon, though. Not usually the one getting in the middle of the camera wars. Like bikes....both are good options, but it comes down to individual choice.

Back to topic, I will say that all things being equal fit and feel wise, I'd take Ultegra over 105 components any day. That's like putting your money on the good glass over the latest body, photographically speaking.
