People on this site (just look at the name) are very much pro-airline...
Guess it comes down to your goals and what lifestyle you want.
If you like great hotels (you keep the points, NOT CRAPPY AIRPORT HOTELS, OFTEN RESORTS in my experience), rental cars (CREW SHUTTLE, hell no LOL), avoiding security lines, and generally being a bystander for "lifestyles of the rich and famous" then corporate flying tends to be pretty good....have about 5 years doing it...
But be careful, the business tends to be a bit more unstable than the airlines, and pay tends to lag a bit, but quality of life DOES tend (IMO) to be very nice. Me...I went airlines to cargo to corporate, and now back to cargo. It's what I like, but in all honesty corporate is a close second as long as you can handle ypur passenger with EXTREME CARE, a wrong word (simply by accident), about the prior trip to a client in the presence of a wife as opposed to their lover can cause a job loss, etc...unlike the airlines you are on the front lines, dealing with the customer on a regular basis, no buffer....
