Back to the early 90s music weekend

There is this argument on Youtube about comparing Ariana Grande and Mariah Carey. People have been saying that Mariah Carey is the best of all. But I think there is no such thing as being the best for every type of song genre. Mariah can the best for only certain types of song genre such as R&B, for other genre such as for the song If You Ask Me To, Celine Dion easily beats her by being more suitable to sing the song. Everyone has their own place in this world, no one is actually the best for everything. Everyone is special, unique and is the best for being in their place and doing what they do. Comparing is just illogical.
