They're obviously all better at different things, but who in your opinion has the ability to do the MOST out of the four when it comes to dueling/outplay/carrying?
*dueling does not necessarily mean against each other
This is a bad question. There are to many unkowns is asking who does the most for a team. WHat are the other four champs? what is the enemy?
IF you were talking from a first pick senerio i would ask is this a premade or a pub?
Yasuo and Zed are far better in mid lane than top.
I'd say Lee Sin is slightly better than Riven since top lane generally has to build tanky or snowball hard.
I can't vote because all these champions are better mid laners then top laners. In fact, they are all really just mid laners. Even Riven's better off mid (she gets thrashed royally by top laners in general)
Lee Sin is the exception, but Lee Sin isn't a carry. He's an early game powerhouse who turns into a support.
The only top lane 'carries' I can think of are 
and 
. Who can both outduel just about anyone else in the game, and while Jax is superior in a teamfight, Quinn can splitpush incredibly well and murder anyone whos out of position in an instant.
