28mm 1.8 vs 24mm 1.4 AF

[jaayres20]

I have the 28mm 1.8 and I mostly use it at wedding receptions and am pretty happy with it. I think it does well at focusing fast in low light which is a must for me. I am not satisfied with the image quality in comparison to my other L lenses. I am interested in the 24mm 1.4 but I am concerned it won't focus as fast as the 28mm. I ran into that with the 50mm 1.2 not focusing as fast as the 50mm 1.4. Anyone with both lenses?

24L seems to focus rather quickly for me in dim light on a 5D Mark III. Haven't used it with the 1D4 yet though.
