I can tell you this.... I have have had fun on both for me the hang up is this.... I can't afford to have a snowmobile , a separate snowbike, and a dirt bike.... Where I live I like taking trips in the winter to the desert and I am too lazy to convert the bike 5 times during the winter for those trips... Now I can snowmobile out from my house also.... I is about a 3 to 5 mile road ride and for me the snowmobile is much more pleasant to make it to the backcountry.... Again I agree with the others if you can have both that is the sweet spot.
