I'd rather see the Dark Reign/Iron Patriot version of Osborn. Spider-Man himself has said that Osborn is at his most dangerous when he keeps his maniacal Goblin persona under control. He then has full access to his considerable intelligence and becomes a terrifyingly effective schemer.
The Green Goblin is rarely regarded in-universe as a heavyweight Big Bad, precisely because he spends so much time and energy obsessed with Spider-Man. Dark Reign and Siege showed exactly how lethal Osborn can be when he channels his psychopathy into pure lust for power.
- Manipulates public perception during Dark Reign, and his killing of the Skrull Queen to redeem himself in the public eye and become a, "Hero".
- Takes over SHIELD, renames it HAMMER(for no reason other than it sounds cool)and effectively becomes America's, "Top Cop".
- Modifies one of Iron Man's suits and takes on the identity of the Iron Patriot, a combination of both Iron Man and Captain America.
- Recruits his own, "Dark Avengers", made up of the worst Super-Villains he can find, including Bullseye, Daken(Wolverine's son)and Venom(Matt Gargen/Scorpion). He also manages to gaslight The Sentry, a being who is implied to be the literal Wrath of God, into being his personal living weapon.
- Kills thousands of innocent civilians in a bombing which he then blames on Asgardians. Which gives him the excuse to attack Asgard itself, eventually causing it to crash into the ground.
