Which Michelin Tire? Defender LTX M/S or LTX Winter

This year I had Costco to install the latest and greatest Michelin M&S tire as I did not even get one year out of the LTX??? last year. I am done with Michelin Tires. I have purchased a new set of Michelins for many years and they are riding on their reputation now, not their quality of years past, just my opinion. My next set will be something else. Again, just my experience and opinion. JH
