it all depends on what you want to do
for me, if I'm a regional pilot and a fortune 20 company offers me a Gulfstream and/or Global pilot position and UA/AA/DL/SW called, I'd go with the corporate job, hands down
If Walmart offers me a Lear Jet position in Little Rock, and a major called, I'd go to a major
many many scenarios
I'd leave Netjets for one of 2 fligt-departments in a New York minute
