- OOTB went #1 in zero countries, Animal went #1 in 3.
- Tok sold more than IKAG but IKAG went #1 in more countries than Tik Tok.
- Hot N Cold destroyed Blah Blah Blah.
- YLIMD destroyed Thinking Of You.
- Waking Up In Vegas and Take It Off were both moderate hits.
- The albums themselves both had mixed reception.
- They both won Best New Act at the EMAs, but Katy also won a Brit Award, a PCA, and had two Grammy nods.
- Ke$ha's tour grossed more than Katy's.
- OOTB is at like 3.5 million worldwide while Animal is at like 2.3 million.(?)
Overall they were both really good and pretty head-to-head but I'll go with OOTB because it's sold more.
