Good Houston gas stations?

Moving from FL to Houston in 2 days. One of the main things I will miss is Wawa. I don’t eat any gas station food but if I ever do I will only get food from Wawa (or salad from 7/11), and the free air is very convenient. Is there any gas stations similar to Wawa in Houston? Or any ones that are obviously better overall quality & convenience than most? I think I remember seeing a Racetrac when I was out there and I hope they have 7/11 lol. Or are they all pretty much the same?
