Can’t really speak from a pilots perspective, but for me choosing between the two was a simple as asking myself one question – do I want to be a military pilot or a civil/commercial/airline pilot? If your answer is the former, then go mil. If it’s the latter, then concentrate your efforts in that direction. I chose the latter, and that’s what I'm working towards and hopefully I’ll achieve one day!
Yep, there are many commercial pilots out there who came from military backgrounds. But I’m sure, and I’d hope, they wouldn’t have seen military flying as a mere stepping stone into commercial flying. If you continue your education to the university level and decide going military, consider joining one of the UAS units.
Most important thing - do lots of research! Searching here is a good place to start and peruse appropriate threads in the military aircrew forum. Visit your local military careers centre and have a chat with the guys down there.
Good luck with everything
