As for the Ag paints, I prefer Van Sickle it seems to have a bit better UV resistance but they are pretty close. I personally don't think any of them are much better than good 'ol rust-o-leum unless you use a hardener. The rust-o-leum seams to dry slower though. For the best of both worlds you can use the hardener meant for Valspar Ag paints with rust-o-leum, or likely any oil base enamel, if you don't mind working with the isocyanates. Going that way lets you get a custom color as many places carry the rust-o-leum bases and can custom tint them.
Personally I would rather avoid the risk of the hardeners and just deal with repainting the item after a couple of years if needed. If I really need a hard finish I will take it to a body shop where they are set up to deal with it. Alternatively I would take it to a powder coater, but we don't have anyone close by in my neck of the woods. A good primer makes all the difference in the world, as does using a phosphor etch if not using a self-etching primer. This seems to really help with both adhesion and rust resistance. One trick that I have used while avoiding the hardeners is to either bake the enamels in the over, or use heat lamps or the sun on larger pieces to get the surface temperature up. It seems that by curing them a bit faster they get to the hardness level that you don't see for a couple of months otherwise. Oh, and the spray bombs of rust-o-leum seem to take almost 10 times longer to get nice and durable in comparison to the pints, quarts, gallons. I suppose it is all of the extra solvent?
