It comes down to your style. They're both good lenses, but I'd go with the 24-70 myself between those. But that's solely because I like the focal range. I don't think you can go wrong with either of them.
Don't worry about what they're cropped to. The crop factor will affect both lenses if you wanted to find the 35mm field of view equivalent. Unless you switch back and forth from FF or 35mm to crop it's not really going to affect you. You know what 24mm is like on your crop camera, why worry what it's like in a format you're not currently using?
