Lady Gaga. I really liked Brit, but mid way through Circus she lost me when I realized she just couldn't give a crap. Her older stuff is great, but Gaga is the real deal.
Lady Gaga. Better personality, better discography, better music videos, better connection to her fans, more talented, more Grammys, the list goes on and on. Britney's work was great back in the day.
