It'd be fun to swim around as a Zora with the Zora Mask. The All-Night Mask would help me when I'm on a coding binge. There are a few times I wish I had the Stone Mask. The Keaton Mask is just cool. The Bremen Mask not only looks cool but involves great music.
But if I were to pick one mask that would affect my life the most, it'd be the Mask of Truth. Being a mask that represents truth is enough to interest me, but discerning the thoughts of animals would also be an interesting ability. I think it would lead to a greater understanding and appreciation of the universe. I'd be wary of using it with humans though. On the one hand, seeing into people's hearts and minds would help understand them better. Then I can understand them and not judge them. On the other hand, it might just give me more reason to judge, and there's the obvious issue of privacy. I'd probably ask for permission first, and offer the other person to borrow the mask in return.
