They literally rap NOTHING alike. Only thing similar is their passion as far as rap style
But their rhyme styles, their delivery, subject matter, flow, cadences, are drastically different.
As a big fan of both I think there’s a lot of similarities between X and Pac
Aggressive, bald, tatted up, stayed with his shirt off, rocked bandanas and leather vests, yelled on songs and dissed nikkas in a brazen way similar to Pac
X rapped a lot about death, the devil, the struggle, etc like Pac and he would write story/metaphor joints like Damien and The Convo like Pac
Not to mention Dee & Wah have that flick with Pac in 96
Also if you listen to X pre-RR demo shyt, you can see that they took a page out of Pac’s book to rebrand him. I think it just worked because of who X naturally is, so it didn’t feel fake like Ja
