In contrast the Canon 24-70 f/2.8 L II clearly loses to the Canon 70-200 f/2.8 IS II at 70mm f/2.8:
Don't rely on the dtp tests too much at pixel level, they usually only test one lens sample and there's a wider production spread, so if the 70-200L2 or 24-70L2 is sharper @70mm depends on your individual lenses.
Personally, I'll get the Tamron 24-70vc because I don't need to rely on cps, I don't need f2.8 all the time (it's sharper stopped down), the Canon mk2 w/o IS is more than double (!) the price and vc is useful even for shooting people when they're posing for candids. Imho the main applications for the new Canon are photojournalism and such where the objects are moving and fast af is important and for landscape if corner to corner sharpness is required.
