I was faced with the same decision and chose the 35 1.4. It has a great shallow DOF quality at 1.4 for head and shoulders portraits with the 5D. If I need 24mm during a wedding or engagement session, I use my 24-70 (which is just as sharp as a prime even at 2.8).
Just my 2cents...the 24-70 is definitely not as sharp as a prime, at least in my own experience! But it is great that you like the 24-70...
Brae, just a question, are you worried that the 24 might be too wide for you and that's why the 35 is in the running? Or are you wanting feedback on actual lens quality?
You know I love my 24... It will definitely have a wider look than the 35... The 35 will have less distortion so it might be helpful for some of the formal shots or when you want to shoot wide without it really looking wide...
But if you are in to the really wide look with a little distortion, I'd go with the 24. It has awesome color and contrast and is super duper sharp. I have not had experience with the 35 though so I am not qualified to give my opinion on lens quality comparisons...
Maybe rent/borrow both to see what you like?
