I'll have to add my vote for the Michelins. Quiet, long-lasting, tows well, awesome wet traction. They (in my experience) can get you through the snow if you need for them to, and because they're on a 4Runner, the do it better than most, but it's not ideal. If you have two to four snows a year like I do here in NC, go with the LTX M/S2. I love mine. At 90k miles, I just replaced the set that came after the original dunlops.
Just make sure you keep them aired up properly to get the 75k miles out of them.
