If you're going to be doing a lot of commercial mowing, light duty mowers won't hold up over the long haul. Sustained commercial mowing will take the life out of medium duty mowers in due time. The new BUsh Hog SQ172 is what BH rates as "standard duty". (In between light and medium) For the price difference, I'd lean towards the 296 (new model replacing old 286)
Around here, Bush Hog has more dealers. That translates to more competition. That means a better price usually. I own 2 Bush Hog mowers now (286 and 2615 Legend), and 1 more on the way. I was able to buy a Bush Hog medium duty 2 years ago (286) for the same price as a Rhino light duty mower. I've got a 307 Bush Hog on the way. (heavy duty) It priced out quite a bit less than comparable Rhino mowers. The 307 will replace a Woods BB840 that's going away. Eventually, a new 306 will replace my other Woods, an MD172 that's been nothing but trouble since day one.
When you get on into heavy duty and extreme heavy duty mowers, Rhino quality takes a back seat to NO ONE.
After using Bush Hog medium duty mowers along side of Woods medium duty mowers, no contest. Woods isn't on my list anymore. They look nice and the blades are easy to change. After 500 hours of mowing none of them are pretty any longer. I very seldom ever take blades off the mowers. They don't hold up nearly as well as Bush Hog in hard everyday use (gearbox troubles) . So the "advantages" of Woods are a wash.
My choice, all things being equal, Bush Hog. Just make certain you buy a model heavy enough for your intentions. If you go too light duty, brand won't make much difference. They all break if used too hard.
