Well the way I look at it, Im bout to say screw them ALL!!! Im sick of EA and Im sick of Activision. There are indy companies developing games as good as, if not better. I don't need no stinkin' ranking system crap. Hell I still love to go old school and play RTCW, a game over 10 years old that is still hella fun.
A couple of games I recommend people look at, especially you John, since you will probably want to add these to your list of available games.
Ravaged - http://www.2dawn.com/
Rekoil - http://www.rekoil.com
Both are MP only, PC only, and are releasing the dedicated server files to the public. Rekoil is releasing all necessary mod tools as well, so that game should do exceptionally well. I already have the beta for Ravaged and waiting for the games release so I can have a server. I applied for the beta for Rekoil and hope to check that out soon as well.
Personally, I will not be buying BO2 and most likely nothing from Activision ever again. I am so tired of the crap. FWIW there are cracked ranked servers for BC2, BF3, Crysis 2, BO, MW3, MW2 etc etc. Its not like anything they are doing has even slowed down, let alone stopped the piracy they seem to be looking to thwart. They need to get a clue. I personally intend to vote with my wallet.
