The problem with cool jetpacks is they’d burn your legs off.
To get around this, the jetpack thrusters have to be displaced from the back. That makes the jetpack cool in that flying is cool, but it doesn’t look as cool as the Rocketeer.
The Rocketeer holds the peak of jetpack aesthetics.
Marvel’s Falcon isn’t a jetpack user. He’s got wings. I understand that in some iterations his wing-pack has jets, but it’s a totally different aesthetic.
