Do yourself a favor if you can get your hands on one, get the Silverburst and get drunk afterwards. As a professional Luthier and lots of Studio work under my belt, I own 1963 Gold Top Les Paul with super humbuckers and which i have added active electronics myself. Having said this, the silverburst is the closest thing to my vintage Gibson. I own a few gibson and had occasion to try mostly all the new Gibson including the GT. The GT is nice but for the price, you wold be better off going on e-bay and but a second hand Les Paul . The value will get be more on this second hand over time. My Gibson is valued between $12,000 to $22,000. Okat I have to admit it is in good shape and old. But to answer your question, again, the Silverburst is a must. Better hurry up because Gibsom plans to discontinue this guitar verrrrrrrrrrry soon. Why ?? So that anybody who has one, will be able to auction if off at a high selling price. Forget the GT....hardware is bad, the frets need filing and the body, is krap.

I'm personaly not crazy about gibson and find them overrated, and sometimes don't live up to the name. but to figure it out maybe you should go on youtube type in the guitars title and watch some people play each of them. Thats a good way to see if they have the sound you like, both being from the same contributer they will probly have a similar feel.
