Should you shut down or sleep your macbook?

I have heard a lot of varying answers to this question when I look it up online, but I still do not have a definite answer, so is it better to sleep your Macbook or shut it down completely?
That's just a personal opinion.

I sleep it down and reboot from time to time (less than once a week).
