It's not the other quests are not as good, it's just I for one love the kind of epic quests where you have to contain and defeat never-ending waves of ennemies. It is fun, difficult, rewarding, and looks balanced. Grats!
On a related note, the updated Trogs quest is a lot cooler as you can't just run through it in 5 minutes flat, never stopping, and there's more variety in areas.
