It depends on where you're going and how. If you keep the guitar with you all the time(or at least under close scrutiny)the gig bag is easier to travel with. But if you have to put it in baggage, a harfd shell case is the way to go. I use gig bags for most of my instruments bedause if you're going out with more than one and you don't have a roadie(or a car for that matter)the gig bag is the way to go.
