Both are better than the inpatient family med teams schedule. 8a-8pm, day of rounds/floor work (no admits, go home when done with your patients), than either 2 10a-11p or 2 8p-8a (plus FM cross coverage) shifts followed by a day off. No better way to kill a circadian rhythm.
That's an interesting schedule. Off topic but based on your sig I assume you decided upon EM?
