How do you personally spot the difference?

What do you like and how?

Do you remember a awfully sounding guitar? How was it?

This is just asking people to list guitars that they like and don't like?

People spot the difference by playing them, and having opinions. "How" doesn't make any sense.

These threads are pointless and aren't allowed. There's already a low-effort "three favorites" thread going on now, that's more than enough.
