I`ve used POR 15 but not the other two,which one is better?

I've used POR and Rust Encapsulator, but not Rust Bullet.  I've also used Zero Rust and it's my current favorite for a single stage paint.  My order of preference would be Zero Rust, Rust Encapsulator, and then POR (if I it were all I had.)

Zero Rust is a lot cheaper and available in more colors so I think I`m gonna try it.
