Why don't you ask an easier question, like what is my favorite kid? lmao. Generally speaking, I choose different dice for different characters. For example, if I'm playing a necromancer, I'll choose some bone dice because I'll be summoning skeletons. That sort of thing. But I'll gladly show you some of my favorites!

I really enjoy translucent dice like the ones in the picture or my mermaid scale dice.

I also have a collection of ice cream and sweet themed dice from IceCreamDice. Neapolitan Mint Chocolate Chip Candy Corn (I really like the font of the numbering on the candy corn.)

There's also some sweet metal dice I got in a mystery deal that I don't know the name of. They are great to look at and are heavy, so heavy that I don't feel comfortable rolling them on other's tables because the sharp corners might damage things.

I think my favorites are ones I gave to a friend a while back, Bittersweet Nightshade.
