on the not great part. Her vocal control is TOO great not to be considered great. but you are right...she has a lane & isn't very versatile either.
When it comes to
putting on a SHOW
Beyonce is number 1.

can sing, dance, fill up a stadium with her voice, can wild out & still maintain discipline. Can be dope..then classy. Uses props...does everything good. I can't hate
2. Fantasia. she's just a crowd pleaser, versatile vocally can sell just about any song, has dopeness...lacks classiness. can't dance, more of a homerun hitter, constantly swings for the fences (can knock it out the park but at the expense of lacking major vocal discipline...but Commands the stage and audience like none in the game right now.
I haven't seen Adele in concert so I can't comment on her show, but that VOICE is beast....and great enough to entertain anyone with an ear.
3. Jhud...is like watching paint dry in concert. Has poor stage presence & can't entertain you outside of her singing...but only knows how to sing in one dynamic...loud.

Her voice is awesome & powerful though

fills the arena up.
Lianne La Havas (beautiful voice, maybe the best in the game right now) great control, soothing. Haven't seen her live in concert either so I can't judge her show or how versatile she is.
