This is a tough one, because 75% of these suck.

Gen 1 has classics like the original Geodude line, Onix, Rhydon, and Lord Helix.
Gen 2 has Tyranitar and... Magcargo would be decent if not for that horrendous typing.

Yeah, that leads me to why Rock-types are usually awful: Their weakness profile is the most crippling of any. Water, Grass, Ground, Fighting, AND Steel is particularly terrible. There's a reason a majority of these Pokemon have at least one 4x weakness. Rock/Ground to Water AND Grass, Rock/Water to Grass, Fire/Rock to Water AND Ground, Rock/Dark to Fighting, Rock/Steel to Fighting AND Ground, Rock/Electric to Ground, Rock/Ice to Fighting AND Steel...

Yeah, looking at that, there's a reason Rock is among my least favorite types. They really could've done without the weakness to Ground. I never played Sword, only Shield, but the idea of there being a Rock-type gym so late in the game is not a good one. I've heard people say that Gordie is among the weakest gym leaders they've ever faced; Melony is considerably better, since I at least had a halfway decent fight with her.

I guess I'll just vote for the gen where I like the designs the best.
