Differences between Mage Hand, Unseen Servant and Find Familiar [closed]

I’m playing LMoP at the moment as a player and I’m trying to see reasons why a player would choose Unseen Servant over Find Familiar. Related question – what makes Unseen Servant worth taking instead of Mage Hand?

Here’s a small comparison table I’ve created when I was trying to figure it out. I do understand that different DMs can rule things differently, but still I’m looking for opinions.
