Do you think it's important for a song to have a hook? Not necessarily a chorus, but like a little figure or "motif" that sticks out. Like that Bb-C-C riff (Bah dum dum!) from Hit Me Baby One More Time? Or all those guitar parts that open up Beatles songs (Something, In My Life, I Want To Hold Your Hand, Sgt Peppers, etc)? Or that repeating vocal line that opens Uptown Funk? Is it most effective to start the song with the hook?
you will have to try it different ways and see what happens
