The key word there being "about." I really don't think those two tires are super close in performance, but perhaps close in performance per dollar.
I will definitely be going with the Goodyear F1 for my next set of tires. Tirerack did a head to head scientific test on identical cars and found the F1s to be virtually identical to the S-03s. As WagonMonster said, they are way cheaper than the S-03s as well.
