So far I like what can be done with Polar. I even tried it on a sample and it sounds pretty dope. It's cool on live vocals too. I wasn't sure about Etch until I saw how it basically gave the factory sounds more life. I don't know much about synth modeling and effects and what not, but I imagine the people who make the refills for reason will have more tools to work with. So I'll wait to see what they make. I guess Korg's Polysix will come later along with more developers like Rob Papen's Preditor which is due to come. I think it's dope, can't really complain, atleast I can try them out for free.
