If your into mud riding, you might want to consider the Grizzly with the diff lock, otherwise i'd go with the Rancher AT with IRS, EPS, and Traxlox. The wife has one, it was a good trail machine until I did a gear change on it, now she can play in the mud whenever she wants too. The problem I found with the Rancher is that it is geared for trail riding and is geared way too high for slow, mud crawling or water crossings. With the gear change it turned it into an entirely different beast.
My next wheeler is probably going to be a 700 Grizzly since Honda doesn't want to build a Foreman with IRS.
