The Marshall Mathers LP and The Eminem Show both tied.
The Marshall Mathers LP is a masterpiece. The lyrical content talks about Eminem's hard childhood , fame, american society and against the people who disrespect eminem. It has excellent dark and hardcore beats and eminem just dominant every track espically "Criminal".
The only songs I remember when I was a little kid was The Real Slim Shady, Stan and The Way I Am.
On the other hand....The Eminem Show another classic eminem album. It's more lighter than his The Marshall Mathers LP. He talks about race, terrisoms and more personal life with his family. His rapping skills are amazing and quite witty, ironic too. The beats are dope. I use to see him alot in his music videos such as Superman, Without Me, Cleaning out my Closet and Sing for the moment.
