I would guess it's much like the guy driving the 15 year old beater car making fun of the guy who drives the 20 year old beater car....but secretly hating him because the guy with the 20 year old car has a hotter girlfriend.

Mesa clearly has much nicer equipment than Skywest (who still have turboprops and 50 seaters) and you know the girls always go after the guys with the larger equipment. ;-)
