Boxing is a great sport and I am a big fan but saying boxers are better strikers then MMA fighters is kind of retarded.  People are always like put an MMA in a boxing match and he wouldn't last a second, well the same can be said for boxers in an MMA match so really the argument is really not applicable.  Conveniently people always bring up Mercer vs Sylvia but I can bring up Couture vs Toney which for me was basically the same thing.  For one the stance a boxer uses is different to that of an MMA fighter because he doesn't have to worry about sprawling for takedown's, having to work from the clinch and checking leg kicks. 

 

Personally, I think the best strikers in the world are kickboxers, preferably guys that do K1.  Guys like Semy Schilt, Badr Hari, Remy Bonjasky, Tyrone Sponge, Gohkan Saki, Peter Aerts, etc.  Not to mention when these guys fight for the K1 Grand-Prix they end up fighting 3 to 4 kickboxing matches in one night to win the championship.  Overeem actually has excellent striking for an MMA fighter and he won the last K1 Grand Prix although in my opinion he got lucky because of the draw he received and the fact that Badr Hari was suspended.
