I've used them all, this is my opinion...
14-24G vs. 16-35L II = 14-24G sharper and less distortion but the 16-35 has the more user friendly range IMO.
24-70G vs. 24-70L = 24-70G and it's not even close
70-200G II vs. 70-200L II = Draw, both are great
85 1.4G vs. Sigma 85 vs. Canon 85 1.2L II = 85/1.2 IMO, the other two are comparable.
The only lens in this bunch I wouldn't want is the Canon 24-70L, all the others are really great optically.
Im thinking of adding D800, 14-24G, 24-70G, Canon 70-200 II (for 5D), and either the Nikon 85 1.4G or the Canon 85L II. Lucky for me I still have a long time to decide.
