I think the QOL is very good overall, but of course that is dependent on your preferences. I prefer to work as little at possible and maximize days off. On average I am home 18 days a month. I rarely go out for 14 days in a row though that is what most folks here prefer to do. Hotels are generally 4star or better for layovers over 30 hours.
We do have a few ppl leaving for UPS and FEDX and some retirements, very rare to have someone leave to return to the legacy jobs.
