If I were buying a 35 MM lens today, I'd get the Canon 35F2 IS. I already have the old Canon 35F2. For my current use, it is fine.
I don't really need wider than F2, and I'd like the IS and USM AF of the new Canon.
My current camera bodies don't microadjust, and so I don't see a need to gamble on an F1.4 lens at this focal length.
I tend to prefer Canon color rendition, and I would certainly want to wait for more reviews before considering any new lenses. All of these lenses are expensive, and I am not in a hurry.
Frankly, most "popular" or "liked" doesn't always mean "best." More people like big Macs than the food in fine restaurants, so I don't make my choices of camera gear on the basis of what is popular. I tend to decide in terms of my photographic wants.
