Influential to other rappers that would be Drakeo, if not just that they influenced each other. Cause besides one song, he wasn't much bigger.
He had a generic not so LA style that was easy to emulate, and dumb music gravitates towards dumb rappers, that tend to be copy cats.
As far as influencing people, in terms of mindset, thought process etc. it's obviously Nipsey. And his style was very distinct, hard to ever sound like him without sounding like you're doing a karaoke. But you can hear influence in people like Kendrick and Jay-z as far as content goes.
