Welcome to the forum!
The difference between the Conti and the Michelin is subtle, but there was a trade-off between a few characteristics. I loved the Conti, but they lasted about 30k miles. I honestly could have taken them legally to 35k, or maybe a little further. I wanted a reputable mileage tire, so I went with the Michelins this time. What I lost was a little bit of watershed on the roadway, and picked up some road noise on smoother pavement with the Michelins. Both are negative trade-off's that I'm ok with, they are minimal. I'm happy with the tire overall, and have clicked a bunch of miles on them and they still look new!
