Which is better? Kohler Command or Briggs and Stratton Vanguard?

Buying a new ZT lawnmower and can get a pretty equal deal between the two mowers I have in mind. However, 1 is used (3 years old and 150 hours) and has a briggs vanguard and the other one is new and has a kohler command. Any help is appreciated. Thanks.|||My personal preference would be Kohler Command as i've used one before.|||The debate between Briggs %26amp; Stratton and Kohler can be summed up in another more common battle, Ford vs. Chevy. Some swear by them, others swear at them. Both engines are good, so don't let the engine be the deciding factor. My personal preference is the Briggs.
