Is there any way you could shadow in each role for a day and see what you like best? OR circulating is not for everyone, but some love it. PACU nursing will vary depending on the type of surgical facility. An inpatient PACU that recovers ICU level and pediatric patients will likely be more intense than one that recovers primarily elective, simple surgical adults.
There is something to be said for no weekends and holidays, but that also depends on your current lifestyle and living situation. If you have children or are planning a family in the near future, for example, there are many benefits to M-F. If your ultimate goal is to travel through nursing assignments, experience in a widely-applicable speciality like PACU May give you more options.
It's all relative. I'd start by asking to shadow and see what work environment feels like it's a better fit for you.
