Yes I have had both, the 24mm F/1.4L II is much better. I would wait for the 24-70mm II.

Did you compare at the same aperture. The 24mm F/1.4 beats the 24-70mm at F/2.8. The 24mm F/1.4 can shoot at F/1.4, but just like the 35mm the quality of your picture drops off significantly. At F/2.8 it is very good.
