I think you can use any of them: quote from Nikon "The 70-200mm f/2.8G ED-IF AF-S VR supports the TC-14EII, TC-17E II, TC-20EII".
But which is best? I'd say, stick with the TC-14EII or, if you feel you need it, the TC-17E II...skip the TC-20EII but you might try the TC-20EIII if your body can cope with autofocusing at higher f numbers.
As for pros and cons; they will almost certainly soften your shots, autofocusing will probably be slower (if it works at all), you lose a stop or more of exposure...you'll get a 420 mm equivalent focal length on a DX body (TC-14).
The optimum solution might be to borrow one (or another) and try it out first.
