Gator makes great gig bags; I own the one that has hard sides that accommodates my DN, and formerly my GA. Tough, light, and really "solid" protection (though the backpack straps
really suck, which I fixed by replacing them with an excellent pair of backpack straps from Amazon for $14). That said, their Transit series gets lots of love from folks who use those, too. Gator is a great company that I've used over many years and would not hesitate a bit, though you may want to buy from a place that will allow you easy return (Sweetwater, Amazon, et.al.) should the fit not be to your liking.
FWIW, if you're feeling like you want the gold standard in a guitar bag, go with either Mono or Reunion Blues. I have two Mono bags (for electric) and the level of protection and their overall build quality
are the reason they are so pricey. But if you consider the cost of the guitar you're protecting, the cost of these high-quality bags comes into perspective rather easily, IMHO! I've not had personal experience with Reunion Blues but they enjoy the same stellar reputation as Mono. Hope that helps you a bit
