Best OS for Macbook pro 2013

Hello everyone I had macbook pro 15” late 2013. I was installing the Sequoia its runs ok, just bit slow at first desktop loading

But I find something annoying. When I move files into my NAS, the finder mostly gives up. I must hard reset to get normal again

There was no problem with my other macbook air and imac with default OS

So anyone know what is the best maximum os for my macbook pro late 2013. Because I might be downgrading it
