Here's how
Politifact rates it (for the parts they've checked, which doesn't include Romney's lie about seeking out women's groups.)
Obama
3 True
3 Mostly true
1 Half true
2 False
Romney
1 True
2 Mostly true
3 Half true
1 Pants on Fire
So Obama has 66% true or mostly true compared to 43% (and likely to decrease) for Romney.
Politifact is a Pulitzer Prize-winning source.
PS. That doesn't even mention the number of times that Romney mentioned how the deficit increased under Obama. I was very surprised that Obama didn't mention the fact that one of the biggest reasons is because he finally put the two wars on the books. I guess he didn't want to be accused of "blaming Bush", even though the increase is clearly due in great part to Bush.
