MoP was a very close second in terms of leveling for me, but I missed all the zones not having a cinematic, and some of them felt like slogs at parts (Especially Valley of the Four Winds and some parts of Kun-Lai), but overall MoP still did everything else better.
Jade Forest remains to be one of my favorite questing zones of all time. It's going to be very difficult for me to skip out on questing in Pandaria on my alts.
