Carl's Jr. tops my list of burgers

I've yet to find a MAJOR hamburger chain to match Carl's Jr. YMMV and I want to know what you think. I used to really think JIB was good, but they have went downhill. I stopped in Kerrville and ate a burger at Wendy's and it was disappointing also. Surprisingly DQ's Beltbuster is very very good. Okay, I know someone will post about a local place, but that is not what this is about. Its about your take on a MAJOR chain. Opinions?
