Both lenses are very good performers. For me, the main consideration would be which one best suits my preference in terms of focal length. That, of course, is a personal decision so the fact that I went for the 35mm may not be relevant to your choice.
Why not spend some time with your 24-70mm zoom set to 24mm then 35mm to see which length works best for you?
