French fries ... they are all ok, but I'd have to say Wendy's has the slight Edge.
Chicken Nuggets, Wendys by far, they are spicier.
Nugget Sauce, they all have options, so this is a draw IMO.
Small Burger .... Wendys Double Stack is good. I don't eat burgers < 1/4 pound unless they get sold by the 10 sack or from a castle.
Large Burger .... Fast food places do not serve large burgers. (Large being > 1 pound of beef.) The Wendys tripple or BQ tripple Whopper are decent, but I do not consider them to be truly "large."
Chicken Sandwich ... Wendys Spicy is probably my favorite. When it comes to grilled or regular breaded .. I'd take McDonalds.
Breakfast ... McDonalds FTW.
Never had Salad, Fish Sandwich, Desert from any of them
Wendy's Chilli > Onion Rings
I dunno if it's still on there, but Wendys used to have the Double Stack on their value menu, as well as the chilli and biggie fries. 2 double stacks, 1 biggie fry, 1 small chilli, and 1 medium drink make a decent sized (horribly unhealthy) meal for just $5 +tax.
