I would think you'd say First Blood II is the over the top one? Definitely is the case for me anyway, but yes I have to take Commando over Cobra. Not just because of Arnold but also the awesome cast of villains, Vernon Wells rules man. Mad Max 2!
Honestly, Commando is my childhood.
I grew up on Arnie. Terminator 2 is as far as I can recall my first film as a kid of about 5.
Favourite actors in order include: Arnold Schwarzenegger, Charlton Heston, Clint Eastwood, Charles Bronson, Robert De Niro, Al Pacino, Pam Grier, Helen Mirren, Meryl Streep.
I honestly can't even think of an action film actor more overly masculine than Arnold Schwarzenegger.
PS: Toshiro rules!
