LOL!
This has nothing to do with brand allegiance or fanboy antics. I give credit where credit is due... and Nikon deserves credit with the 14-24.
There is no lens out there, that can do what it can do. It's been that way for a good while now, and I certainly, keep hoping that Canon will have an answer for it someday, but as of yet, it is still unrivaled by anyone and hence, deserving of the title of "legendary".
I wasn't the one who introduced 'fanboy' here.
Is the 14-24 a great lens? Yes but if you don't need those 2mm on the wide end both the Nikon 16-35 and Tokina 16-28 are also good. Unlike some, I like to try things for myself and have the rental bills to prove it. In this case I won't be trying the 14-24 because of several reasons, 1) cost 2) I don't shoot wider than 24mm on FF often and 3) I'm not a pro by my definition of what a pro is. The Tokina was cheap enough to try, if I don't like it I'll buy the Nikon 16-35 VR and be done with it.
Switching now
When compared to the Nikon 14-24 in IQ and corner performance, the Nikon is without a doubt the better performer. Why do you think I sold my 16-35 II to go out of my way to adapt it to EOS? 
I've seen what it's capable of and there's nothing that can come close at similar FLs.
