Case choice very personal and depends on how you are going to transport. I have quite a few, here is my opinion, take it for what it cost.
Chinese Aluminum. Junk but good enough for the trunk of the car. American Box store plastic. Bit better than the Chinese Aluminum and good thing is they are light weight. Either Car Trunk or used to ship a gun mailed when sold, wrapped in cardboard outside.
My Pelicans used for target rifles have been checked on Airlines dozens of times. One multiple times International with no issues. So heavy I rarely use them unless I need to fly. Overkill for Take down shotguns except You can take the foam out and put half a dozen light fabric cased SxS guns in a Pelican for back of truck carry chained to the Bed.
Best buy protection for the money is a used Americase. They will re-furbish old ones and sell or sometimes give you replacement locks and handles. Fellow at our gun club was throwing out a two long gun Americase most of the hardware was broken or bent. Full of Airline stickers. Said he took it to Africa dozen times. I replaced locks handles and feet cleaned up the outside and it's a safe carrier if not pretty.
SxS case I use the most is Americase two gun take down, 36 inches built for Auto's, bought used and re-configured by Americase for two SxS's, Holds 32 inch 10 G Hammer guns & looks like new.
