I guess the very vast difference is what kind of lifestyle you want.
A bizjet guy typically doesn't get a rooster, but are on call if the boss / client feels like flying somewhere.
Usually it's schemes like 7on/7off etc....but can also be 1 month on 1 month off. Vast difference of lifestyle (not saying better or worse!!) compared to airline.
Plus, I'm sure with bizjets you'll see more places, not just the usual airline routes.

I think it's not easy to get hired into corporate jets though.... most jobs are not even advertised, but people who know people recommend pilots. Very hard to get in as a low-timer I guess. Important clients want experienced crew usually
