Which hand is greater in poker 3 sevens over 2 kings or fives Aces?

Here's how to break down the poker hands and determine which is best:

* Three of a Kind (3 Sevens): This hand is a lower-ranking three of a kind.

* Two Pair (Kings and Fives): This hand beats three of a kind because it has two sets of matching cards.

* Four of a Kind (Four Aces): This hand is the strongest of the three, as it has four matching cards.

Therefore, the best hand is Four of a Kind (Four Aces).
