The Scorpion may (very contentiously) be a bit stronger and has some nicer toys, but he simply lacks Lizard's savage urge to kill, his healing factor, his natural weapons, and the Lizard has recently acquired some new tricks himself. Sooner or later, that armour will break, but Scorpion can do nothing to the Lizard that he can't shrug off and heal from, and once Curtis makes a breach in the armour, he's going to force it open and eat the poor sap inside.
