Which composer is regarded as one of the world's greatest composers of all time?

In my opinion I think Mozart has every composer beat because he was a child prodigy playing harpsichord and violin when he was 4 and a genius (he was good at math and he knew 5 languages). But people are more familiar with Beethoven because of his symphony 5, ode to joy, moonlight sonata, and I also like his symphony 7 and so that's why people say he is the best but I still think there will be no one else like or better than Mozart with his Turkish March, coloratura soprano Queen of the night aria from the magic flute and his well put together requiem. (I still like a lot of other composers and have over a 150 songs on my YouTube playlist)
