Sound:
I would have to say that my Gibsom SJ-200 is one of my favorites. Before I go into the guitars suddelties and nuances, I should preface it by acknowledging that my SJ-200 is a limited edition piece. It is #22 of 46. So this description is given under the probability that all SJ's are pretty much the same. The Maple back & side gives it a deep rich sound but is brighter than a Rosewood dreadnought. One thing I find cool about the SJ-200, is how light it is. It is at least half the weight of my Martin D-41. The sound is soothing for a jumbo. The action is great but I think I had it adjusted after i got it but I can't remember? The one thing to watch out for is humidity control. I've noticed that the humidity affects the sound of the SJ as much as any guitar I have. And I have 33. All acoustic or acoustic/electric. My SJ has the most beautiful Quilted maple you ever see. It is a gorgious piece from top to bottom.

Ease of Use:
Has a great sound but to much humidity dampens it.

Support:
I haven't had any dealings with Gibson. Ever.

Overall:
I'll never get rid of my SJ.
