Also, in terms of contrast and flare control any comparisons?
Since you have mentioned that at 70mm, the 28-105mm is sharper at wide open (5.6). I am assuming that you are mentioning 24-70mm also wide open (F2.8) at this focal length or are they at the same aperture (F5.6)?
Check out our reviews for those comparisons.
Both lenses are capable of taking great photos. IMO the key factors for deciding between the two are price, weight, and whether or not you need F2.8. If you need something that's good corner-to-corner, that's where primes step in. Another thing I'll add- if you want the VF to be very bright, i.e. for manual focusing or if you don't live in a sunny place, perhaps the F2.8 lens would be better.
Personally I've opted for the 28-105mm as my walkaround lens.
