How do you handle the distribution of household chores between you and your SO?

How do you handle the distribution of household chores between you and your SO?
We split all household chores evenly
S/he does the chores they are best at, and I do what I'm best at, we sometimes rotate
We rotate chores so no one person has to do all of one thing all the time
I prefer to do X chores, because I know s/he prefers to do the other X chores, we don't rotate
We both agree in hiring someone else to do the household chores
We just argue back and fourth until someone breaks down and does the chores
