I have an 800 polaris ranger.
will fit 3 grown men across the front seat.
was main selling point for me, several of brands have 2 bucket seats in front.
as far a rear diff, it has 4x4, both back wheels pulling, or 1 wheel pulling, selectable by switch.
brands are like asking about trucks, ford vs chevy vs dodge.
deer camp I'm in, there is 4 rangers, no problems with any of them.
