In terms of what?

Acting: Aaliyah
Singing: Rihanna
Entertaining: Aaliyah

Rihanna.

This has been done many time before and does not need to be done again
Anyway my answer is Rihanna

Two queens. But I'll go with Aaliyah.

Aaliyah was a better singer, better dancer, a better actor and better-looking. Rihanna has better songs though.

I prefer Rihanna but love Aaliyah too

"Rihanna is Aaliyah reincarnated"

Chill sis, I almost had a meeting with that beautiful report button of yours.

Rihanna

You picked one of Aaliyah's worst performances... I mean shade is in order (and you tried it on her death day, desperate and pathetic ) But it doesn't really matter, Aaliyah slayed and won the poll, as always.

But I mean, obviously, the better singer is Aaliyah. Look up her Ballad performances
Better dancer: Aaliyah obviously
and Acting: Aaliyah

Enough said (no pun)

Aaliyah

Rihanna. I never really got into Aaliyah's material.

Rihanna's Career speaks for itself.... Aaliyah never even had a top 15 album on the Billboard 200, let alone a Grammy, or a successful tour. If it wasn't for her tragic death (RIP) she would currently be scraping for relevancy just like Monica & Brandy are.

you can forsee the future? Beyonce scraping for relevancy?

This is an insult. How dare you

Who said anything about Beyonce?
