Continentals are junk IMO. And I wouldn't fully trust revews/servey numbers when trying to compare them. Most of those reviews are meaningless. IE: take someone who buys their first set of "ultra high performance summer tires" coming from all-seasons, whatever summer tire they purchase, they'll likely rate really high because they will find the tires have a higher level of grip. But, that doesn't mean the tires are great. That is just a new level of grip to the owner..
The Yokohama's have a better tread pattern for evacuating water and they have a lower rated tread wear number(UTQG) which means they are more likely to have a softer, stickier compound.
