The one with GRAMMYs.

Because the amount of sales and streams it had were enough to make it reach #8 on the Billboard Hot 100. Not that difficult to understand

Read the OP again. It asks for who is the most successful solo artist, too. Try better when you attempT again.

50k sales and like 4million US views of the audio posted on the YouTube?

charts doesnt matter because if they did, 11 top 10s as solo > 10 top 10s as a solo and the answer would be factually Gaga.

Katy

katy is an entertainer not an artist gaga and not even comparable

PF alone ***** all over any top 10 Katy single ever

Dope performance @ Youtube awards was viewed like 9M times in the first 24-36h, that was the reason that debuted at #8.

Here's Billboard clarifying for you why it went #8 http://m.billboard.com/entry/view/id/72908

Katy

Katy's music is better, more diverse and fresher.

Because the OP totally didn't make this thread to brag about Gaga's amount of SOLO Top 10's, right?

And there's no 'clearly' here, many people prefer Katy's music, cut this gross pretentious attitude.

The critics disagrees.

I agree.

Still letting critics decide on your opinion for you?

OT: Katy

Roar and Firework are her two best selling songs - may I add that they're both Diamond & do not have features.

Obviously not if that's not the question of the thread.
