Playlist for quickest XP?

Which Infinity playlist would be best for those who just want to rank up fast?

As in, most XP per hour?

dunno about playlist BUT spartan ops is the best for me

i’ve only played CTF, slayer and dominion however on average i get about 2k a match

spartan ops gives me about 4.5k!

Flood is netting me the quickest XP. Games are short and you always get 1.5k+ XP

I think the first chapter of Spartan Ops.
