Why do you always seem like you have something against Ariana
I think you might be confused, I love Ariana but there's a reason why that pre-recorded whistle was there and why she always lip-sync her Baby I's whistle too.
I'm still a fan tho.
Beyonce is a better vocalist, but she's also almost 12 years older than her giving her 12 more years of experience. Ariana at the age of 20 is a far better vocalist than Bey was at the age of 20. If Ariana can develop, protect and create her own special vocal moments she'll edge Bey out in the long run.
Beyonce's lower registry > Ariana's.
Ariana's chest voice > Beyonce's.
Head/Falsetto - I'd probably give to Bey or say it's a tie.
And Ariana can whistle.
Beyoncé by far. Ariana has great potential but she isn't on Bey's level just yet. Ariana only her whistle register over Bey and even there she needs work. Beyoncé trumps Ariana in every other aspect
