My advice without knowing all the details and based on my own experience: go for the commercial. I did a few years the swap from bizz jet to the airline and i never regret my choice for a split of a second. Bizz jet was for me too much of a pain. No life, always getting called on my off days, changing rosters (and thus off days) without asking etc. I dont miss those days AT ALL. Even Netjets is for me a no-go!
