For some years I've been wrestling with this question, since the lovely Helen (ever so lamented in her absence) recommended The Mighty Boosh to me*, but I have decided.
Vince Noir is fucking hot, right down to the (admittedly) incredible hair. Noel Fielding, on the other hand, who has more than once been sighted in the company of Amy W(h)inehouse, is not.
A contributing factor that is by no means exclusive to him is the hipster belt that wraps oh-so-clingingly-and-oh-so-inviting-of-the-rimming 'round the lower part of his arse. Frankly, it does wonders for anyone height/weight proportional, but he can work that shit, down.
The whole post-modern-awareness bit is almost but not quite gilding the lilly.
And I'm happy with this sort of dichotomy, as the exact opposite (actor v. character) holds true for David Tennant, and comes damn close to working for Chris Eccleston.
*The reruns of The IT Crowd on IFC have helped in this as well, as well as complicating my idea of just how cute Richard Ayoude is after Garth Marenghi's various incarnations (but that can be tied back to the Emotionally Feckless Fucker...). Turns out he's straight, but still... cute is as cute does.
