Is that Phil Goetz's CEV vs. all humans' CEV, or Phil Goetz's current preferences or behaviour-function vs. the average of all humans' current preferences or behaviour-functions? In the former scenario, I'd prefer the global CEV (if I were confident that it would work as stated), but in the latter, even without me remembering much about Phil and his views other than that he appears to be an intelligent educated Westerner who can be expected to be fairly reliably careful about potentially world-changing actions, I'd probably feel safer with him as world dictator than with a worldwide direct democracy automatically polling everyone in the world on what to do, considering the kinds of humans who currently make up a large majority of the population.
