Tough one, but Rayleigh's the one with the most experience and we've seen him fight on par with an Admiral. That counts for something.

i thhinkk dragon since he has a devil fruit and haki

To run a rebellion you'd have to be pretty damn strong. I'd say he's the stronger one, but we haven't really seen him 'fight' before.

dragon is strong..but reiyleigh actually went hiding after rogers death...........not bcz he is weak...........he is a master of haki................my bets on reyleigh........he he he eh e

dragon!!!!!!!

Based on lack of info about Dragon. And if you say 'Dragon is going toe to toe with the World Goverment' Rayleigh doesn't care to do anything. He has been doing nothing for 20 years.

Dragon, because Garp probably trained him to be a marine capable of taking on the giants of the old age, Rayleigh included.
lol Garps dream of having a marine as a son was shattered when Dragon instead chose to fight the world government instead of serving them.

Gonna have to go with Rayleigh. What Whiteflame said, I agree with.

Prime or old raylegh?imo dragon beats prime raylegh so i vote him
