I did 15 years of corporate /135 work. IF you find a great company, I don't think there's anything better. That means more pilots than planes (24/7/365 problem), the right size plane (G-IV, V's, Falcon 900's, etc. - you usually go overseas a lot and are gone for longer periods of time), a good Owner, a good Aviation Manager and Chief Pilot.

The only problem with corporate is if it's a company or individual that falls on hard times financially (or dies), the planes are the first things to go.

Some of the biggest and most stable companies have closed their flight departments overnight.

The best gig I heard of was a guaranteed job for life by a single Owner and a $5 MM life insurance policy on the Owner naming the pilot as the benefactor. Single pilot King Air 200, living in Idaho and making six figures.

I'd walk out on 20+ years of seniority at any airline for that kind of job.
