You didn't mention Honda Pioneer, but after having a wide variety of machines I STRONGLY perfer the Honda for 2 reasons.
1. GEARS! It isn't a CVT. The Kawasaki Teryx we had was a CVT so the faster you went the higher RPSs were - and louder it got. My Pioneer will shift, and it's a thing of beauty. I will ride for miles down gravel roads, and being able to have it shift to top gear and then just put along is a really valuable feature. I will never own a CVT again. My Teryx was a very sensitive go pedal, it was pretty tricky to keep it smooth especially when doing chores. The Honda has none of those issues
2. SOUND. The pioneer is much quieter, partially dependent on the transmission and partially beacuse it's just a quieter machine.
I'll keep buying Pioneers until they aren't as great as they are now
