Also US, and largely agree, but I would move Hardee’s/ Carl’s Jr. Down to bottom tier. That’s also where I’d put Jack in the Box. I’d put both In-n-Out and Whataburger as mid tier - I think both are VASTLY overrated.
Though In-n-Out is owned by a Christian Nationalist that’s hell-bent on turning America into (more of) a fascist oligarchy and openly using their wealth to destroy democracy, so they’re on my boycott list, along with Chick-fil-A.
This is the best primer over ever found on the topic
