Quick summary of the Tire Rack data:
The Continentals are slightly better in the wet, the Michelins are slightly better in the dry. Treadwear will be better on the Continentals, steering response better on the Michelins.
The Contintentals cost nearly half that of the Michelins, which is good value for those getting the Michelins now, but easier on the pocketbook to replace a flat for those with the Continentals.
Both good tires from good companies, just different tradeoffs.
