We compare an offsuit hand with a pocket pair. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead.

That is a slim edge: neither hand is far ahead. 0.63% of boards are ties, so the equity of each hand is its win rate plus half of that.

In the ranking of all 169 starting hands, KTo is number 33 and 44 is number 48.
