Silver Age Superman has far better feats than just those. He also survived an explosion equal to the Big Bang, as well as being MFTL+ to the level where he could fly across the universe in seconds (enough to blitz Vados easily). With the Sword of Superman, he's essentially a walking plot device, as it's capable of reality warping as well Omnipresence and Omniscience, as absorbing all of it would've made Superman one with the universe, with the only reason he didn't absorb it being that it was unnecessary.
Without the Sword of Superman, Vados wins with high difficulty, mainly in trying to combat Superman's speed. With the sword, they're about equal in power, though Superman's reality warping and Nigh-Omnipresence make it a stomp match.
