T-Pain > Drake, Nate Dogg, Future, Kirko, The Dream, and just about anybody else in that field of music. I legit think Pain may be one of the most underrated musicians of my generation. Love what he's able to with his catchy songwriting and melodies. Pumps out hits in his sleep.
And while i'm on the subject, the best hooksmiths doing it right now IMO are Ty$ and PARTYNEXTDOOR. Drake as well, but I favor them when i'm trying to listen to what is basically singers who sing rap verses and bars
