I'm a Lessie and I definately prefer the Standard. Hell, I had an Epiphone, but that wasn't enough, tough that was a pretty good guitar for the money.
I think that the Standard (or Classic, Custom) have more sustain and richer sound. The Studio is more like and extra guitar in my opinion. If a had one, I would keep it and tune it for slide i.ex.
Of cause, the Standard is heavy, but HEY, that's the price of being a Rock n' Roller!!! :D
Peace
