Exmark, John Deere, Everride, Lesco, Scag, Redhawk, Toro, Walker, Bob-cat, Swisher?????

Which is by far, hands-down, the best commercial walkbehind mower manufacturer?
Gear drive or Hydrostatic?
What is the most productive/manuverable/easy to operate? Fixed deck of floating?
Sulky or no sulky?

I am in the market to buy the best walkbehind, I would buy a Honda if they made a commercial walkbehind, but instead I currently use Honda Harmonies and a John Deere rider.

I need some insight.

Thank you.
