Please learn to spell Britney's name properly.
I love Taylor and she'll clearly be one of the most remembered artists of this generation, but no one can beat peak Britney. You can say Britney is a flop, a casino act, etc but you won't erase her legacy, when she was on top she was untouchable, she had too many iconic moments that Taylor hasn't had and she was a global artist from the beginning, Taylor only became global during the 1989 era.
