"Ado is the best singer of all time" What's your opinion on this statement?

I'm not exactly asking about wheter you think she has the best songs or not bc that's too hard to tell. What I mean by "singer" is having singing skill, vocal range, and basically the ability to make magic with their voice in inimaginable ways (I have no idea about theorical music lol). There's been many singers out there with amazing songs, but I'm truly wondering if she's the best one speaking of singing skills.
