BUYING GUIDE: Acoustic Guitar Gig Bags
This bag has minimal padding but it's affordable.
This bag has a pretty decent amount of padding (20mm) and it can take some abuse. This bag would probably be my choice if I had something like an FS800.
This bag has a lot of padding (30mm). It's pretty darn rugged and can take some serious abuse. Your guitar might survive a drop on the ground in this bag. It's built to last. It is going to be a bit heavier than the "Better" option.
This is the best of both worlds, protection of a hard case with the ease of transport of a gig bag. I would give this case the nod over all those other hard cases if you say dropped your guitar off a 3 story building. It's expensive. It's heavy. But it's rock solid and built to take a serious beating.
