2 Chainz and Flo Rida squared off at this weekend’s BET Awards … and one of them won by a neck.

Both showed up with giant jewel-encrusted chains … it’s debatable who’s got the bigger and badder bling … but both look like they could cover a kid’s college tuition.

One thing’s for sure … sometimes one is enough … even for 2 Chainz.
