I have seen storm cases hold up the best compared to pelican for equipment at work. Generally latches fail first after being shipped dozens of times.
For personal use, I decided on a Pelican 1720 for flying. The 1750 is quite large to drag around and I was able to fit everything I wanted in the 1720 with about 1/2" to spare. Measure carefully if buying to fit a specific size firearm.
