Fuji XF 35mm 1.4 vs other 50mm lens

I just ordered a silver body X-E1 saturday, hopefully it's on it's way.  I want to pair it with the 35mm 1.4. I was wondering the 35mm 1.4 stacks up against some of the best 50mm lens such as (Nikon, Canon, as well as Leica 50MMs) ?  And is it really optical wise and image quality wise the best out of the 4 fuji lens that's available (vs 60mm, 18mm, 18-55mm) ?
