I can't speak for the Michelins but the Goodyear F1 All Seasons are great as long as they have tread which in my case wasn't for long. The F1 All Season lasted less than 16k and that is taking them below the treadwear bars. This is my wife's car and she is a very easy driver and drives mostly straight country roads slightly over the 55 mph posted limits. How they get a treadwear rating of 420 is beyond me
If you go with the Michelins I'd be interested to hear what kind of mileage they give you.
