12 hour night shift, 4 on 4 off or 4 on 3 off question.

If you did 12 hour night shift work, would you rather do 6pm-6am 4 days on 4 days off. Or 3pm-3am MON-THUR (Friday, Sat and Sunday off).

The 4 days off sounds nice, but always having the weekend off plus Friday seems good for a social life, also it seems you would be waking up at 12pm (lunch time) for work, so on your weekend +Friday you would still get the afternoon to yourself. Also if you finish at 3am you would get to sleep when its still dark, making in "easier" and on the weekend you could even go to bed early (2am) and get a good sleep when its dark. The only downside is that its a 48 hour work week and 3 days off might not be enough to recover. Also over the course of a year you would be working an additional 25, 12 hour shifts. (Yes I know more money)

I guess as you guys have experience in nightshift and likely work 12 hours which would you pick.
