I voted for Janelle Monae. I love Lana's lyrics and studio voice, but she's certainly bland and vapid when it comes to stage presence, vocals, and even style. I do like her vintage-retro image, but I think that if you're gonna rely on your style to represent the artistry of your lyrics and set up a whole scenario, the least you can do to pull off a great performance is to polish your vocals skills to go along with it.
Her vocals are extremely weak, and off most the times, which kills the mood in her performances and makes them lack of emotion.
Example: Adele. She also plays to put a simple, slick, classy scene but she knows how to back it up with her vocals.
No critics, just putting my opinion out there.-
