OK, I'll bite...
The critical Michelin user reviews on this forum and others (Tire Rack, etc) are generally by users who have either had Michelin tires installed from the factory OR purchased them as after market replacements.
As a longtime Michelin buyer (mostly SUV variants), I decided against Michelin replacement tires (Premier, Primacy, Pilot, etc) when I replaced my factory Bridgestone's early.
I elected to fit both my 2014.5 Camry SE and my wife's 2011 CR-V with Pirelli tires. I had never purchased Pirelli tires before but after extensive research, I was very comfortable in making the switch to Pirelli's. After driving nearly 25,000 miles on my Pirelli's on the Camry, I LOVE them. I drove home from Dallas very early this morning in torrential rain and they were great. They plowed thru the water as if they were new. In February, I had them in heavy snow and black ice and they were quite good, for an all-season tire, with a very firm compound. Overall, my Camry has never driven so well-confident grip, quiet, wear very well (approx 7-8/32 remaining). Granted, I have not put Michelin running shoes on it though for comparison purposes.
Michelin makes great tires to be sure. Reportedly, they also vary greatly, within the product lines offered, as user reports verify. The Premier looks to be a very promising new-gen tire, but not enough data was available for me to select it. The Defender looks great on paper, till you see user reports in hot climates where longevity seems to be an issue.
When I replace the run-flats on my Corvette, I will probably strongly consider Michelin's . It is ALMOST always, a pretty SAFE choice, though it may not be the BEST choice, for the specific application. You can be sure, it is ALMOST always the most EXPENSIVE choice.
Like anything else- YMMV. Consider the source as you read the critical reviews across the venues and then make your own judgment.
