Me as well, used DOF PRO 10-15 years ago, back in the days when rendering true DOF was unthinkable. Even though i liked its results, novadays i wouldn't even consider fake DOF, unless you're rendering animation, or for some specific reason really need to make it in post.
P.S. keep in mind that for the best results, you need to render aliased z-depth pass, at least that was requirement when i used the plugin in the past.
