What about taking all three?
A SPOT for your friends and family to track your adventure. An EPIRB for emergency use, and a Sat phone for someone to contact you once you press that button.
The real question is whether an rescue infrastructure is in place to quickly come to your aid. When you press that button, will a squad of Marines start dropping out of a helicopter 30 seconds or 30 days later. I'm sure the pressing of the button is detected somewhere within milli-seconds, but it could be hours before your help arrives.
