Corporate pilot perks: nice kit ( it really is a shiny jet), you rarely go to work. Downside: always on call so no real days off, you are the one who has to shine the jet, you do all your own planning and catering, if you piss off the boss or shag his wife/girlfriend/fantasy you get fired, you get to clean the toilet after flight, and despite cleaning it, when the shareholders revolt you still get fired.
Airline pilot perks: guaranteed time off, as long as you don't crash you are unlikely to be fired, others do planning/scheduling/catering/cleaning, the biggest decision you make in flight is the chicken or beef, when you complete the shut down checklist you are done for the day, it really is money for nothing chicks for free. Downside: none that I ever noticed.
Does your hypothetical mate really have the luxury of such a choice?
Or pilot dreaming?
