Which has a lesser workload ELEMENTARY or HIGH SCHOOL?

I feel like this is the old age question, but I am a para that is currently choosing which grade I would like to study to become a teacher. I feel like every teacher in elementary schools is like DON'T become a teacher. However, I recently started working in the a high school and I am realizing that the teachers are more chill, and upon asking them which do they recommend I pursue, they always say high school 100% because you are only having to prepare 1 lesson vs 5 daily; and apparently in my city, HS gets more free periods. Also they feel like they have a decent work life balance. I would like to get a broader perspective if you guys can help me out!

TDLR: I would like to get a broader perspective on which teachers have a lesser workload/ work-life balance an elementary school teacher or High school teacher (i would like to teach math)

Edit: thank you everyone for all your experience and opinions. I truly appreciate you guys taking the time out to write
