I've only had a couple of gig bags, and as much as I used to gig, I'm soooo glad that I stuck with hardshell cases. Stuff just gets thrown, dropped, slammed, & such, especially when you're not looking, and I have soooo much more piece of mind knowing that my instruments are safely suspended in foam between 2 hard surfaces. My siggy gtr has had the same plywood case for nearly 14 years, and well over 500 performances, and while the case looks scuffed as all get out, the guitar is in fantastic shape considering how old it is. The guys at Warmoth can attest to that from me bringing it to work several times when I worked there. I also have an SKB keyboard case with the wheels at one end, and it's saved my Synth from many potential catastrophe's over the 13 years I've had it, so the $225.00 that I spent on it back then has more than paid for itself.
