Your work is much less without them in many cases. You peace in your own damn house is significantly elevated.
The walking around on eggshells is gone.
The fits are gone.
The constantly picking up is gone, because without them working against you with their laziness, your children will learn to pick up after themselves pretty quickly as long as there's a place for everything and everything gets put in its place. And it's a consistent habit.
The constant refereeing is gone. Stupid competition just to make a competition out of every damn thing. Gone.
The household runs more smoothly.
The begging and pleading for help or basic respect. Gone. Nagging. Gone.
The diet yo-yo you find yourself on because he won't eat anything except burgers and pizza. Gone. You won't even try to have to lose down to a healthy weight. It'll just fall off by eating normally. That means all your insulin resistence health problems also evaporate. Even PMS gets better or disappears.
You can work out. Uninterrupted. You can make a game out of it with the kiddos. Primal movement games.
YOU get to be the fun parent for fucking once. And only to the people you actually birthed.
The benefits of ditching all the man drama cannot be understated.
