I ran a pair of Blitz cans for years and they were fine, they have no more problems than any other steel container that can eventually rust if you let the paint go bad. However, Blitz jerry cans have an internal coating that makes them not suitable for water so I bought a European 5 gallon water container and it fit my Blitz jerry can holder perfectly well.
You can kinda see it on the driver's side of my spare tire carrier, you can see the Blitz jerry can holder at the bottom of the tan water container.

I'd suggest looking real hard for some Scepter MFC's. They're not CARB-approved now that some rules changed so they're much harder to find. Once you do the Viton gasket swap for the gasoline fuel, it's the last can you'll ever have to buy. Scepter Can, MFC review and test
The no longer offer cans that will fit the standard pour nozzle. If you get these you will need to use a siphon most likely. That is how I use mine most of the time anyway. As a way to get around being able to sell cans of this type new they had to use non standard sized pour spouts. Makes no sense but hey F**k California CARB compliance.
