We have Michelin M&S 20" on our Expedition, they do not look very aggressive which is fine for me as its an Expedition I think aggressive would look stupid on it. Lots of Sipes which give you great traction and I get excellent wear so the price is worth it. I'm in Buffalo NY and been through Feet of snow visit my Daughter in Colorado been snowboarding in Mountain's truck goes through anything on unplowed paved and stone roads. We never really need to do any muddy off road stuff I would guess they would not do too well in that situation. Plenty of dry off roading in CO to lakes and such does fine there.
