Geodude

Geodude is a decent Stealth Rock user, as its Sturdy ability in conjunction with a Berry Juice usually guarantees that it will set up Stealth Rock. However, it is largely outclassed by Onix in this role, as its superior Speed stat, unpredictability in ability options, and access to more utility moves like Taunt and Roar make it function much better as an entry hazard lead. Geodude does boast a far greater Attack stat and a nice movepool, though, containing Sucker Punch as a priority option, a very powerful Explosion, Counter to smack physical attacking foes back, and great STAB moves to take advantage of Geodude's amazing offensive typing, all of which give it a good offensive presence and make it function as a better suicide lead for offense teams. Like Onix, Geodude suffers with a bad Special Defense stat and mediocre HP stat, which coupled by its terrible defensive typing that gives it a 4x weakness to Water and Grass as well as other weaknesses to common types like Fighting and Ground, makes it mediocre defensively, though Sturdy does mitigate this hindrance.
