FL430 in the "large" corporate jet I fly (occasionally) has Cabin Altitude of +/- 3500 feet.
Crew food is good too.
Not being flippant, I used to fly A320,330 and 340. I always felt "dry as a bone" by the end of a long day and regularly had ear pops. Especially on the A320.
Flying is bad for you whatever. Try to do as little as possible is my aim.
