Both. Mostly jets but when I was doing planning for the Wing, I flew with a USAF LtCol in a piston.
Okay, then I say we are in “violent” agreement.
Land a good margin, as you say, with jet engines on board.
Land much closer to stall, perhaps a few knots over, for piston.
A piston you can recover a porpoising landing.
A jet you should do a bounce-n-go, and try again from scratch, due to spool-up latency.
