In the tC I see marginally better mpgs from Sunoco than Wawa, but typically not enough to make a difference to the cost/mile. Locally those are the only two places I will fill up. In the absence of those two I will seek out Shell or Chevron. I will actively avoid BP, Exxon/Mobil, and Lukoil because of environmental/political reasons (not looking to start a n argument or debate the rationality of my choice, just making a statement).
