Gonna have to go with either Team Deathmatch, or Domination. Both are pretty fun, and offer up the highest player base so waiting for a lobby is almost non-existent. However, a few of the other game modes are kind of dumb in my opinion. Cranked is a bit of a joke, especially with how awful the connections have been lately, and it really comes down to a Free For All mentality, even though it's a team based game. Since YOU need to get another kill within 30 seconds or you die. Blitz is definitely an interesting concept, but the maps are heavily one sided, often times making it incredibly easier for one team to score more during one round then the other.
