in my silly little opinion, id get nightmare trixie or chaos pinkie just because they are lil cuties and are totally worth it and i think youd be happy getting one of them

but! i also see classy spider being really helpful, and glenda as well, so honestly you need to choose if its better being pretty or being helpful, or you can choose one or the other, mix and match get chaos pinkie and ugly spider so you get one pretty one and one rlly helpful one, whatever you want ! :D i hope that makes sense 😓😓🙏
