The reality is only a few All-rounders mons does actually punish crappy lineups.
Machomp does wins 1v1 but can't follow up after killing one on larger clashes.
Charizard is a Press ZL to win the character and barely functions outside that.
Even when Garchomp got rebalanced, he's still kind of bad because not only does his Ability does anything since the amount of lifesteal is still larger than the amount of reflected damage, there's still no consistent way for him to stick to his opponent to take advantage of his 5-stacked boosted Attack except for picking Dig and probably using XSpeed.
On the other end of the spectrum, Lucario is just too overpowered not because he's strong but because he is able to get away from situations that would normally punish jumping in at a wrong time. He normally wins in 1v1 clashes not because he's powerful but he has enough bulk and crowd control (Boosted Attack) to outlast his opponent.
