The fight between Leatherface and Benny also at the end of the film while they're in a pond with a running chainsaw still on was pretty awesome too. Leatherface wins by shoving Benny's head into the chainsaw blade. Though, the end result depends if you go by the released ending where Benny somehow survives with just a flesh wound. or the alternative ending where Benny does die.
