Advantages of plastic over metal cans (and the reasons why I stick with plastic)
1. They won't rust and taint your gas in long term storage.
2. They won't create a static spark, possibly burning down whatever it is you're putting fuel in.
3. They don't explode like metal cans can (they melt) when exposed to fire.
4. They're much lighter to lift if you're transporting in a BajaRack.
Some folks have said metal will hold up better in outdoor conditions (UV can cause plastic to crack), but they're so much cheaper than metal cans that the cost outweighs the concerns.
Just some things to consider.
