I've been to several Sheetz (including the HQ in Altoona, PA; and RaceTracs, but never the Wawa. We musn't leave out Buc-ee's, either, but they're more of a competitor to Luvs and the big truck stops. I'll still give a slight edge to QT in most cases, mostly just based off of employee service than the store itself. Not an exciting leg of your jouney, lol. Blackwell isn't exactly a mecca of beautiful geography, either, but about the first stop inside OK when coming in on I-35.
