I think that's important to state what part of a timezone you currently live in when one states a preference: I am similarly in the very Eastern part of my timezone, and have the same preference.

Perhaps that's most correlated with the choice people might have? Esp since there are studies linked in this discussion that suggest people have better health outcomes (in a few very specific cases, but also winter depression) on the Eastern edges of timezones.
