Jamaican crews didnt always get the best of home grown crews
A great example of this is the situation in philly in the 80's with JBM and the jamaican posse. By all accounts , the Junior Black Mafia , who were basically the sons of Black Mafia members , smashed the jamaicans and kinda ran them out of philly. A great documentary on this
I also dont think that the Jamaicans fair too well against home grown crews that are muslim. Black muslim crews are typically more disciplined and organized
