I’d definitely pick 3.

First of all, if you can only eat with one spoon, you might as well pick a cool-looking one. Imagine being at a social event and people are handing out spoons to eat soup or whatever, and you’re like “no thanks, I always eat with this spoon I brought from home”. That would be kinda cringe and weird if you pick a spoon with a boring basic design. But if you pick the third one with it’s interesting demon handle, it’s gonna make you look mysterious. People are going to wonder and ask you about the story behind the spoon. Women will giggle at you and ask if you’d share the spoon with them.

Secondly, it has the most generally useful shape. Being smaller than the others can be very useful for eating from some containers. It has corners instead of being perfectly round, which allows a bit of scraping. But because the corners are rounded, you don’t have to worry about leaving scratches or carving microplastics out of plastic containers.
