Phaleg Ives versus Senator Armstrong (Metal Gear)

If those two we're to face off against each other to a battle to the death duel, who will be stronger? For those who you know, Senator Amstrong is extremely powerful, he is very physicaly strong thanks to the Nanomachines inside his body that give him immense protection and streigth, but I wonder if all that stuff is strong enough if he was to face off against Phaleg Ives?

She would defeat him physically and in a Rap Battle, too.
