I wouldn't think you would ever come close to a consensus on best burger. Way too many variables and everyone has a unique preference in toppings, size, bun, etc.

FWIW, I like Winsteads, Carl Junior's Western Bacon Cheeseburger, Jack in the Box Sourdough burger, and Johnny Rockets. Oddly enough, I had a prime beef burger in Amman, Jordan this year that I thought was outstanding also.
