I still like the fact this version was sped up a bit from the GH version. Just sounds better to me, sounds like it fits the song better.
I'm not sure if you read my post or not but it seems you have a misunderstood distinction: This isn't a sped-up version. This new leak is how the song is supposed to sound. The pitch in Pac's voice is the same pitch you would hear if there was a camera in the studio with him, and you were listening to the camera recording instead of the song.
The Greatest Hits version is a slowed down version of the original, not the other way around
And I agree, the speed/pitch on the OG sounds way better. Probably because that's actually Pac's voice.

Now if only it was mixed the same way as the GH version.
