One great thing about food is that we all have different tastes and opinions. Our opinions are 100% right to us. Another example is that there are plenty of people who think that nasty deep-dish pizza one gets in Chicago is the best in the world, while others like the thin crust pizza we can find in NYC; personally I like the Greek-style pizza one finds in the Boston area.

Right away someone is going to say "wait, Chicago pizza isn't nasty" but that's not going to make me turn around and say "oh, my mistake it is good". If the OP has tried burgers in his area and not found anything that compares to In-and-Out than that's what's best for him/her.
