You certainly can't go wrong with michelins. I too use 4 snows in the winter. For me, I've always felt a little reticent to spend the extra money for the big M. My S550 came OEM with Continentals - awful, awful tires. I replaced them with Yokohama Avid Envigors, and the car just came alive! I was blown away how much more quiet and the handling improved. On my 92 400E I'm running Kumho ECSTA Platinums. They are 2/3 the price of the Michelins, wear great, handle well enough. I'm happy with them. But this is a very subjective topic. Just know that all tire have very different personalities and will make a big difference in how the car performs and feels.
