I prefer Cap vs the Skull. For Killian vs Stark it required Tony to forget about flight and ranged combat. Just like he forgot to protect his house against something so conventional as a helicopter attack after inviting the Mandarin to attack him. That was unforgivable. Stark should have been ready for anything short of Ultimo.(which would have rocked)
