Leo is an incredibly talented actor. Brad is good too but nowhere near Leo imo. I dont know who is more successful, I think Leo since he's been in more big name movies, has more big name awards, and is praised by the industry which is why it was a running "joke" that he never won an Oscar before because he clearly deserved one.
As for looks... both were absolutely beautiful gods when they were younger and both aged horribly
Brad at least still looks decent though.
