MW3 cause compared to the performance i was doing in MW3 was alot better than BO2. the guns, the perks, the maps and the mechanics of MW3 just worked for me and i did so much better. The servers too!!! Treyarch servers are always laggin and in the lobby in BO2 it says people are joinable and when i try to join them usually it says the servers always full. Which they are but it still says their joinable. PLUS Infinity Ward has decided to be a good guy complany and buy dedicated servers for us lot, meaning hopefully NO MORE LAG <3 plz... *fingers crossed*
