There are the Classic and the Custom. Also the Supreme. Various types of pickups throughout. Most people like the standard, because of the Burstbuckers. They are more like the vintage pickups that came in the original Les Pauls. Some come with the 57 Classics that are also a vintage tone.
The Classic has open coil Humbuckers and are the pickups are a litlle hotter in output.
All of them can be used for Blues or Classic rock. There are various color combos depending on model. You can also get the VOS series of guitars that are made to vintage specifications. They are through the custom shop.
I would go to Gibson.com and surf the various guitars. It is very informative and you get a better feel for the models.
The Blues is alright!
