Well what criteria are you using to make the comparison, or is it just in general? I like Kalimdor better, so Disagree. The Eastern Kingdoms have some cool spots, but Kalimdor has more of an untamed, undiscovered wilderness feel. Note that I have -quested through- pretty much every single zone (pre Cata), with many characters on both factions. Well except Deadwind Pass, which doesn't have quest hubs.
