I'm not in the Apple boat, but I do know what you mean about the Google-iness of Reddit, and more generally the Google-iness of Google. Aside from google.com itself, there's something about everything they design that is very off-putting in a way that's hard to describe.

Lack of whitespace? Google Mail, YouTube, even their help pages are crammed full of content.

To my eye anyway it always looks like Google got the developers to do the design as well (even though that's probably not the case), whereas Apples' designs have a little bit more of an "artistic" feel to them
