For mediums, with factory surface, I would have to say the 5.0 for the simple fact the Aggressive can handle large amounts of oil and is *close* to the GP2. The 5.0 being a polished pearl will get through the heads better while retaining energy for the backend. I will be able to tell you more when I get my 5.0s in for myself. Being particle, they both will be able to handle some carrydown.
