Currently, Gaga > Beyoncé >>> Britney. Britney's videos used to be cutting edge and innovative, now they're really stale tbh. Gaga always comes up with something fresh and memorable, for that, hers are the most effective.
Beyoncé, because of:
- Survivor
- Deja Vu
- Green Light
- Get Me Bodied
- Beautiful Liar
- Single Ladies
- Run The World
- Pretty Hurts
- Ghost
- Haunted
- Drunk In Love
- Blow
- No Angel
- Partition
- Yoncé
- Jealous
- Rocket
- Mine
- ***Flawless
- Superpower
I also perfer Beyonce's music videos because the music is better in my opinion and the artist is prettier to watch.
