What's the best egg in Adopt Me?

I'm curious, what do you consider to be the best egg in the Adopt Me game? Is there a particular type of egg that stands out in terms of rarity, value, or just overall appeal to players? As a player, I'm always looking to get the best possible rewards and I'm wondering if there's a particular egg that's worth going for above all others. Can you give me some insight into the most sought-after eggs in Adopt Me and why they're so popular?
