To address your "how do you guys like it" part of the question: it would be okay if I could stay on one schedule all the time, or for months at a time. But this switching from a week of days to a week of nights (domestic) or switching back and forth every other day (international) is really draining.

I was a cop before flying and we rotated our schedules every three months. That was okay because I adjusted to the schedule in a few days and them kept it for a while.
