McDonalds: Salty and good, but limp on occasion.
Burger King: More actual flavor than McDs. Slightly thicker as well.
Arby's: Very good, especially when dipped in Au Jus.
Checker's/Rally's: Excellently seasoned goodness. Very few serve them like this.
Five Guys: Normal ones are good. Cajun ones are GREAT. You get a whole sackful per order, so share with a group. Burgers are in a league of their own!
