What are your favorites? could it be the Infectious living dead? Or maybe a nice game of Social Slayer, The Intense combat of SWAT snipers? MLG where no noob spams are found?
Personally my favorite is ranked Squad battle, the intense game of Valhalla big team slayer gets the blood pumping as I pull off a triple or overkill from rushing noobs.
My friends and I have one called Mongoose wars, and it's basically where there's two (or more) teams of two people. One person drives the mongoose, and the other is on the back with a sniper rifle and a brute shot. The rules are that you can't kill off of the mongoose, and you only get one chance to splatter someone. So you have to have a good strategy so that you can kill the other team without getting blown up yourself.
Almost every symmetric objective game. Especially CTF on big maps with vehicles. I don´t like slayer that much; it get boring if you play it too much...
