Not when Britney's average Metacritic score is 62 (11 higher than Katy) and is currently on a heavily raved Vegas residency, alongside the fact that she's well-respected and universally loved by all her peers.
Katy Perry in both album acclaim and award success. Come to think of it, has she had any hailed or praised moment in her career outside her payola driven Billboard Hot 100 peaks? Poor thing.

At least Britney Jean has memorable performances and a Grammy.
