I am a pretty new user of Raspberry Pi, and I booted it just once so far.
I used NOOBS to install Raspbian on a microSD card for my RP3. When I wanted to shut it down afterwards, I Googled it to learn the proper way to do so.
My expectation was the shut down button on the GUI drop down menu of Raspbian [see photo below] to be the preferred way. However, it seemed that there wasn't a unanimous decision about the right way to shut it down. Most answers I have found didn't even mention the GUI at all.
So what should I do? Is using the mentioned button OK? Or should I use a command in terminal? Is there really a difference at all?
