Staight Out of Compton by far, but IDRM's right about the album dropping off after the first three songs. However, there were only a few tracks on N4L that I cared to listen to.
Amerikka's Most Wanted is good, but I like Death Certificate better -- Talks about killing Jews (well, just one) and burning down Korean stores. Can't beat that.
One old Ice Cube song that's a guilty pleasure is Jackin' For Beats. The video was funny as well...
