I got my PC360 from Bestbuy. This is my 3rd pair, because I am an idiot that keeps running over the cord with my chair which cuts out the mic. I simply take them back to Bestbuy with the receipt and as long as I am within the 2 years they give me a new one right on the spot (assuming they have it in stock) I now keep the cord above the floor with twist-ties.
Anywho, the difference between the G4ME ONE vs PC360 is that the cable for the G4ME ONE is made of Braided fabric cable which allows it to be much more durable then the PC360 (tho I dunno if it will protect it against chair run-overs lol) but it also comes with that 2 years warranty.
IMO - If you prefer Black Headsets and/or saving money, get the PC360 (just take extra care of the cord).
and if you prefer white, get the G4ME ONE with the extra cord durability.
