I can't but like both. I have to say that I only started to listen to her music during BTW era, and Born This Way was the reason I started to listen to her older music more. It took me some time before I really got into the older stuff. I really like where she's going as an artist and I find her very inspiring in general. Born This Way Ball was amazing, it was the only concert where I've actually cried. Just can't wait ARTPOP.
I like a bit of both since Poker Face was te first song of hers i heard but I didn't really start listening to her music until Born This Way. One of my favorite songs, Marry the Night is newer but I love almost every song on the fame monster!
