Hard to say. I had the EP20s and now have the US made 422 pluses. The new tires are quieter but that's to be expected because there's more tread. Don't notice any difference in mpg. The 422 plus has a long mileage warranty so I wouldn't even consider getting the EP20s. I would think the Michelins are a better tire in terms of everything except mpg. They cost more too.
