gibson les paul studio vintage mahogany

What is the difference between the Pauls?
I wanted a Gibson Les Paul and I saw that there were a lot of different types. This version Study, study vintage mahogany custom faded and aged. I'm confused! I just did a study because it is a cheaper, but I wondered how compared in tone, quality, support, etc in all other Pauls. Can someone explain what each one is like Les Paul? In addition, I have a Gibson SG faded. I wonder what is the difference between that and the rule is that there is a huge price difference. It may be just the finish.
things like tone and have little or no difference. materials with different colors. standard pick-up has a different configuration.
