I've never had to fly with him, but heard some stories. Most of them in ATL are great guys (I don't know any in DTW) and I enjoy flying with them.

The 'one guy' in ATL I was thinking of is the same one who prohibits the use of Vertical Speed, ever, likes to get all preachy in the cockpit, not about religion but about his techniques, and takes himself waaayyy too seriously.
