I shut my computer down whenever I intend to stop using it for more than a couple of hours. So that means every night, and some other times as well. Starting the computer doesn't take very long. So I don't feel like it is a hassle or trouble. Being completely shut down saves a bit of power; and there are other minor benefits.

One benefit is that it prevents accidentally waking the computer in the middle of the night, filling the room with light and noise while I fumble in a tired state trying to shut it down. (Not saying that happens often, but it has happened - and it is not nice.)
