Which gas brand(s) are considered the best?

Do you (or did you) have Irving stations in NH?
Back in the days when my brother and SIL used to spend a lot of time in Maine, they got an Irving credit card because those were just about the only stations in the area where they vacationed.

Yesā€¦thatā€™s my go-to station. A little over a year ago their gas switched to a top-tier gas. They are also one of the cheapest around.
