IMO....they are probably all the same.
Now if you want to use some HM oil, for whatever reason, check out your local Kmart.
While in Orlando, there were plenty of red jugs, in the gallon size, of Valvoline Max Life, HM, Synthetic Blend in the SM on clearance in 5,10w-30 and 10w-40 for $11 a gallon.
This Valvoline ML, HM oil was SM....the really good stuff....with lots of Moly! From what is posted in the VOA and UOA's of ML, HM; the new SN ML oil does not have the great add pack that the SM had.
So you could, if you qualify for the Valvoline program, buy three gallon jugs of ML, HM oil and be entitled to a nice rebate.
You would get a rebate or $15, on your cost of $33, for 3 gallons of Valvoline ML, HM, SM oil on clearance at Kmart. Not a bad deal for some quality HM oil.
