The difference is Franco has ripped apart A and A+ and is still only 18 years old. Greene has done almost nothing professionally to live up to his hype.
I'm not trying to be aggressive but anyone on here who thinks Franco is overrated/valued by some of us should really read up on the kid. It's ridiculous how good he is/could be. There's a reason he's #1 above other studs like Lux and Robert.
