Simplicity(Champion XT), Bad Boy(Maverick) or Dixie Chopper(Magnum HP)

I want to get a zero turn but really want to make the right choice... All these appear to be good mowers but what might make one stand out above the rest?

Simplicity is a B&S engine and 3100 Hydro

Bad Boy Kohler or Kawasaki with 3200 Hydro

Dixie Chopper Kohler or Kawasaki with 3400 Hydro

I have heard that cut quality on dixie is not great, simplicty is very comfortable and stripes nice
