I kinda dislike Fairy because I think its a bit overtuned in gameplay haha, and I'm not too fond of a lot of the designs.

Psychic is another one where the designs are real hit or miss, but I like psychic powers so I don't dislike the type.

This is a tough one. There's something to like about every type imo. I'd probably have to say Fairy, but please not this doesn't mean I hate all Fairy types or something lmao. There are plenty of them I love just plenty I am supremely meh about.
