I tried quite a few (pricey...) brands in the WRX and Redline worked the best. Used 75w90NS w/ some lightweight shockproof mixed in. (this is exclusive to subaru, i wouldnt recommend the 75w90NS for most cars)
Held up better and shifted better than anything else, including royal purple. (never tried motul though)
In my other cars I have used MT-90 and am happy with it. 75w90 in the diff too
if you are just driving on the street, no reason to use spendy gear oil. Either OE oil or Mobil Synthetic should work great.
