Lears were/are supposedly hot rods to fly, and the Dassaults/Gulfstreams always seemed a cut or two above the rest. Other than oddballs like the Citation X, most bizjets seem like Toyotas with wings.
As for corporate, it seems to be to commercial what law is to medicine, aka a medical career is more stable/predictable than one in law, but while you avoid (most of) the lows of a law career, as an MD you will never soar to the salary/work-life balance heights that you can as a lawyer.
Likewise, I'm sure there are plenty of jobs in corporate that make even the worst regionals look good. At the same time though, I don't doubt for a second that there are guys flying corporate pulling >$500k a year because they lucked out and the billionaire they're carting around is a good shit who wants to spread the wealth to the people keeping him and his Falcon/G650/Global Express/BBJ from becoming a flaming crater somewhere.
