I believe that the 70-300L is better at the 70-100 range than the 70-200II - however it may be better colour contrast . However this is personal preference based on A3 prints rather than some scientific test.
That said both lens are top draw - I am happy to have both - mostly the 70-300 goes on the 5DII and the 70-200II goes on the 7D/1D4 due to the use that I make of the different bodies.
In your case, they would have similar lengths and would be substitutes to each other; Interestingly, I was thinking the other way around : 70-200 on the FF for portraits and indoor shots and the 70-300 on the Crop for more reach, I don't need redundancy as much, I want range.
