Ever since my 2015 MBA 11' --- I've been COMMAND + CONTROL + Q'ing when I get to the end of my day. Puts it to sleep. I usually leave it plugged in - goes to sleep nearly instantly.
Even on battery, my 2015 MBA, 2017 MBP, and 2020 MBP lose almost no battery in sleep even across many days. The above posters are right - tech today - it doesn't really matter.
I have a 32GB ram MBP and I really like having everything I had opened the day before instantly available when I start the next day. So I prefer sleep. (CMD+CTRL+Q) then walk away.
