I feel bad now for being argumentative.
I don't know how to give a logical reason for exactly why I dislike Kim, but I really dislike her intensely, and I don't want her to win.

I am pretty much watching the show in hopes that something takes her out.
I dislike Alicia more than Kim, but of the others, I like everyone else better. Now why do I feel that way? Is it really Kim, or does editing want me to dislike her? But ... you like her, and michel likes her, and Pepe, so it is not universal.

OTOH, quite a few people dislike her for the same reasons I have.

In my case, it doesn't help that I loathe the wedding industry in the USA and think big weddings are a colossal waste of money and stressor on relationships. So I do regard Kim as something akin to a pusher when it comes to her business. She seems cold and calculating and she lives by getting people to accept that they need to spend a ton of money to live their dreams.

OK, that part is probably an unfair bias on my part.
