Don't speak Taylor lower level than Katy! You don't know or don't remember? Her 1st Country album (Taylor Swift) is not very famous, but the album 2 (fearless), 3 (speak now), 4 (red) was very successful in sales, awards, reputation.
Until her 1st POP album (1989), it's famous all over the world! and is more success than all of her Country album.
So waiting for success of her next pop album ;)
