Threads like this crack me up. I'll bet 90% of those saying "x is the best!" have never tried half the brand lines out there. Which means they are talking out their butts.
I have no idea who makes the best bags, I haven't tried them all. But I purchased the Pacific Basalt bag from TW and I love it. Very well made, very functional, holds its form well, looks great.
