There is a huge difference that really cannot even be compared in a 250 hour CFI teaching someone to fly a 152 or seminole in very basic aerodynamics/meteorology in VFR pattern hops or the rare actual IMC instruction day or the 80 mile cross country $100 hamburger without even touching class A,B,or C and possibly even D airspace, compared to a high altitude swept wing jet flying in March on a 1000 mile leg from ATL surrounded by thunderstorms to BOS where it is 1/4 mile vis heavy snow and gusty winds under the time restraints/pressures/fatigue/nobody is there to hold my hand of the 121 world.
