These guys actually have a pretty similar style except one of them is much younger and a better wrestler. This is a pretty easy pick for me, I gotta go Francis Marshall to be better literally everywhere.

Erik Silva

Erik Silva is an aggressive grappler who will march you down. He walks forward throwing heavy punches and heavy kicks then looks to get it to the ground. On top he has great pressure and control. Everything he does looks like it hurts and he is consantly focused on damage. He gets wild on his feet with jumping and spinning attacks but its almost like he doesn't take the striking serious and is having fun out there just waiting for it to get to the ground. He is coming off a 2 year layoff after a freak injury against Muhamad Niamov

Francis Marshall

Francis Marshall is a heavy handed grappler who comes forward with power and speed to setup his traditional takedowns and jiu jitsu. He is comfortable striking but almost too comfortable, he will keep his hands low and throw out long jabs and hooks. When he shoots they are well timed and full of energy. He is young in his career and is hit more than he should be, but he does a nice job baiting you into a striking match before shooting blast doubles. He is coming off a close loss to Mairon Santos where he won the grappling exchanges but lost the striking.
