Out of all of them, Gaga has my vote, followed not-so-closely by Beyonce. The reason being that Gaga works the hardest and is the best at what she does out of the people listed. She sings very well, she plays an instrument, produces, writes, composes, performs, dances, directs, sews, glues and sparkles. She has her fingers in every pie of the business that she is expected to be using in order to be responsible for what she does on stage and how she is percieved by her fans.
There are very few acts that tour the entire world at such a pace, there are even fewer who do it whilst taking a recording studio on the road with them... there are none who do it whilst being political activists and social icons trying to use their fame, money, and subsequent power to change the world for the better after their experiences as a child.
She very rarely slates others unless they're being particularly bad mannered, she stands up for what's right. She's educated and well spoken, which is another thing you don't see from people such as Britney Spears and Rihanna.
She gets slated for wearing risque clothes, but why shouldn't she? She has a great body - should she be ashamed of it? No. Does Michael Angelo's David cover up? Does the Venus De Milo? No. We all have nipples, some of us have vaginas - there's nothing wrong with it, and the fact that Gaga is completely unashamed of it is marvellous. She has a great body, but she didn't used to have before the extreme touring - she has a quite average body, but still didn't cover up. Know why? Because she has no illusions about the human body - and that sends the most positive message of all. She is unashamed of showing all of herself - because she's only got one selt, and so have we.
