I take it you're combining it with an FX body and that you want 24mm predominately?
The 14-24 is a masterpiece but as mentioned, the lack of filter attachment might not suit you. Have only read about the 24mm f/1.4, but everything points to it being a very special optic, albeit at a massive price.
If you're looking at 24mm then you'd be as well going for the 24-70mm, unless you want wider - maybe the 16-35mm f/4 might suit you, although some folk seem to think it distorts too much.
The format (FX/DX) is important to know really....
