What is the best general category of Battle Bot (fighting robot)?

Of the 13 categories of fighting robots listed on the web page http://en.wikipedia.org/wiki/Robot_combat#Combat_robot_weaponry_and_design (rammer, wedge, spinner, etc.), what is generally considered to be the best overall category in terms a potential 1-on-1 competition win/loss ratio if say a 220 lb robot was entered into a competition today?

Please qualify your answer with specific reasons why a category would most likely best all others. Thanks in advance!
