The cluster does blow the RZR one away. It was a side to side thing for me was I felt the RZR 1000 wider, but I'm a bigger guy also. I guess I don't remember about which one had more leg room as both felt good in that respect. But the Yamaha has that bigger center console that the RZR does not so I'm sure that plays into it.
I think the shifting really depends on your use. I have a 700 Raptor, when you are out in the open with it (dirt roads, dunes) it rocks and banging through the gears is part of the fun. But when you get into tight trails or backwoods with it or stop and go riding with a large group of people I'd rather be on my Sportsman and not deal with the manual shifting.
