The tracks are the same, the only difference is how they are numbered on the back. Killers goes through 1-14 and Killas goes 1-7 and 1-7 again, kinda like a tape would I guess.
I checked mine and it is the Killa version with tracks 1-7 and 1-7. It's a damn good album. Thanks Jay. Do you kow if one of them is rated "OG" or are both just as rare and pressed at the same time?
