I have just about every current AF Canon L prime between 24mm and 300mm. The 35mm f/1.4L and 85mm f/1.2L II are the best for weddings and stay on my cameras as much as possible. I have several friends who have sent their 50mm f/1.2L's back because the autofocus was so inconsistent and it was recommended to me to not purchase that lens so I'm going to pass that recommendation to you. At the moment I just use the 35mm prime and can crop it to around 50mm easily. If I need the extra focal length I just pull out my 85mm f/1.2L II and skip over the 50mm focal length (recommended if you are on full-frame).
I'm anxiously waiting for Canon to come out with a good 50mm lens. This is the weakest focal length in their line up if you ask me.
Also, if the 35mm f/1.4L gets updated with less CA and weather proofing (why does this lens not have this in the first place?) then I'd say the 35mm f/1.4L II is going to be as close to a perfect prime lens as you can get. Image quality is already amazing.
I've been wanting to pull out all of my primes and do a comparison at night time, maybe that can be my next blog entry. Till then here are some samples:

50L is a awesome lens. Am I the only one here who got a good copy? I prefer it over the 35mm for its classic focal length. I suppose ive always been a fan of Henri cartier bressons subtle painting like perspective of the 50mm. No tricks, just a normal view.
The normal view you get isn't about the 50 fov, it's about the compression you get at 50mm. But yeah, I love it too!
I think the 50 L is a great 50, but then again, I agree with what's being said, the Canon 50's suck (compared to 35 and 85)...
MY dream 50 is the same color and contrast and size+build of the current 50 L, but with the 24 L II AF, and the 35 wide open sharpness and way less CA. And get rid of the fact it's useless sharp at mfd, but great at 4 feet and beyond.
I disagree, I like all the canon 50mm's. I've used them all before and all have there strengths and weaknesses. The 50L is my favorite 50mm of all time currently and i've used tons of different 50mms on 35mm and medium format 80mm's.
