My take:
1) Qf3 lines
2) English attack lines
3) Be2 lines take a distant 3rd
4) Fianchetto lines are prob after that
5) Nb5 lines
If you are comfortable with the fianchetto lines though, you have a practical advantage. I play the taimanov from time to time and I would be out of book against you pretty early on.
The current mainline against the Taimanov is 7.Qf3 it seems what is the second place and where is 6.g3 in that ranking
