I feel like Puff is the most successful artist he's had after BIG and Mase for real but that's a different argument. If we're talking dudes outside of himself, I'd have to go with Rob, Shyne or 112. I guess it's outdated but for me, I'm going to look at the success they contributed to the label and like @
scuba said, it comes down to the math. If the label is putting money into getting him spins and yet not recouping any of it from his album sales or single sales, then it's really moot. The fact that he can do shows is great but his overall impact is going to seem like a blip years form now. BR, Shyne and most certainly 112 can say they had hit singles and at least one high selling album. I know a lot of cats scoff at album sales now but you know who doesn't? Those labels shelling out the money to market and push their artists..but if you're talking impact, then you have to include sales, you can't just focus on one aspect and discard the other. Numbers are the one thing that isn't subjective.
