That depends, if you intend to buy the older versions with server browser ie COD MW4/CoD 2/CoD WAW search for thier population first thru https://www.gametracker.com/search/cod4/.
If you don't mind the random high ping which is a disadvantage for fps, go for black ops 3. Usually the newer versions have the most population
