Janet and Ciara wouldn't be good. Only the crazy Ciara stans think that this is a good idea because they think that Janet is a one trick pony like Ciara. Janet would demolish Ciara. Ciara hasn't done anything, but that ATL crump bs almost 10 years now. Janet has done all types of choreography and mixes up different styles of dance in her routines. As far as voices, they both don't have strong voices, but Janet is the better singer. Whoever is saying that Janet doesn't do anything, but whisper is ignorant. Ciara struggles to push whatever notes she thinks she's hitting whereas Janet knows her limits. Janet can emote, Ciara doesn't even know the definition. Don't let me continue...
