Name another company that even landed orbital class booster on whatever try.
10 years ago it was an impossible feat many were laughing at.

The space shuttle achieved reusable booster landing in the 80s with parachutes and water.
Delta clipper controlled burn relanding in the 90s but not scaled to orbital class.
Nobody with any sense for how rockets work should be impressed with parachuting and refurbing SRB tubes. Landing a proper rocket stage the real way is an impressive feat of robotics and engine engineering. The shuttle SRB thing was a wasteful farce meant to pay lip service to the loftier goals set by earlier Shuttle proposals (such as real flyback boosters.)
A far better example, although still not exactly the same sort of thing, would be landing the SSMEs with every orbiter landing. They obviously required refurbishment (as all Falcon 9 Merlin engines do too) and the propellant tanks were expended, but the engineering that went into the SSMEs is a much better example of precedent to Falcon 9 than dropping spent SRBs on parachutes.
SLS/Artemis is actually using some of the specific SSMEs that have flown before on Shuttles. Veteran engines, but they will be discarded this time, no more refurbing. What a damn shame.
Shame for nostalgia reasons perhaps, these engines were made out of unicorn tears and the price tag reflected that. The new gen methalox engines are much saner economically.
Solid engine booster isn't in the same category of complexity as liquid engine booster, though.
Sure, just saying it wasn't an impossible feat.
