in addition to the mentioned.
all the electronic additions make life even easier. quite smart already the 72-201/202/ series. climb sequence quite easy, turn the power management and retard CL's to 86 %.
with 500's even easier just turn knob.
For flying it never made a difference for me handflying. once i got used to 72's i startet do land the 42 the same way. other way round is difficult. while a 42 lands with the same technique a 72 does not with the technique of a 42.
72 a bit a problem with long landings in tailwind. for short strips I prefer a 42 over a 72. more reserves in flare.
