"Dude, suckin' at something is the first step to being sorta good at something!"

I don't think I'm a very good DM, but all of my players ask me for DM tips when they're doing another game or one-shotting or whatever, so maybe?

Asking a question, then immediately leaving... Who the hell starts a conversation like that!?

Dungeon... Journeyman?

In answer to the question posed by the title, a high maintenance party.

If you where dumb enough to try. Willing to keep going. and put up with our BS, you are favorite DM.

You're only as good a DM as that last session.
