I think my shift is the best for my schedule.
I work a 12 hour shift 7a-7p. Other crews work at alternating times. I work every M & W and every other Fri-Sun.
This means I always have T & Th off, and I have 4-days off every other weekend.
I get paid more per hour than do 24-hour medics at my service, because it is determined that they do less work at certain times during the shift.
I work 3-4 days a week, and can easily pick up overtime on my days off, which is readily available.
The best part, I have every night off to spend with my family, and can take weekend trips whenever I want every couple of weeks.
