It must be so hard to DM. I've never tried, I've only been a party member. I think all the campaigns I've been in have had lots of good bits, so I'm not sure I have a most fun kind, though anything with good storytelling is always interesting.

Basically, I enjoy most of it apart from the nightmare scenario where the party start to argue out of character. That is *the worst*.

But not really a roleplaying thing, specifically, that of course.
