Really one power washer is as good as another. Most all commonly have a Briggs and Stratton motor. And a pump is a pump. What sets them apart is the hore power of the motor and the size of the pump. The average power washer is 1500-2500 psi, with a 5-6hp motor. You best bet is to look at what you intend to clean as to how big of a washer you need to buy. And consider if its got alot or grease and grime would a hot washer work.
