The Nuttso version is the OG. It's pretty much untouched on Better Dayz, except 2Pac says i'm in the studio w/this nigga Nuttso, something like that---they edited out on Better Dayz.
Nuttso was pissed at Bad Azz for trying to claim his version as OG. I have an interview w/Nuttso where he talks about it. Bad Azz finally didn't want any beef and backed down/ admitted his wasn't OG.
2Pac worked alot with up-coming Oakland rappers, and Nuttso was one whom he did several tracks with.
