I think sociology is the more interesting subject, but psychology is the more beneficial one. I guess it depends on what major you plan on pursuing. I was a psychology major, so that's probably why I think that studying it in high school was very beneficial.
I've done both. Sociology is easy but I hated psychology
Mainly because our teacher kept us doing Memory for like a whole year so most of us failed
But do some research on both and see which one you like the look of most
