I know this is way late but...
Voted #1 because marketing-wise it has the best rhythm and cadence. It is smart, simple and gets the message across in one word. Design-wise, and typographically, it lends itself well to being a balanced design both horizontally and vertically as well as a badge or initials. I could also see it using very high contrast, knockout or reversed whitespace.
#2 sounds like a paint color Bob Ross would use…a little bit of Meteorite White for these happy little clouds that live over here...
