Which one is worse??

My First Pet Stuff is a complete cash grab. It's one of the greediest things I've ever seen done with the Sims.

I think Katy Perry Sweet Treats got backlash just because it was a specific celebrity. I feel like if you're a fan of her you'd enjoy the stuff pack but if you don't like her than obviously you wouldn't care for a pack dedicated to her aesthetic. Personally, I think the items from Sweet Treats were fun, new and fantastic quality.
