I'm skeptical - but interested.
DPOS is either superior to POW - or it isn't.
POW is nice because it is truly centralized, but it can never scale because of this.
POW has a big advantage of being a great distribution mechanism in the vital early stages of a coin/DACs growth. Having thousands of miners available to be the first users makes it a whole lot easier to get network effect, especially as the first users are the hardest to get.
