Ironically, nearly all of the albums you listed were blatantly influenced by late 80's/early 90's West Coast Hip Hop.

In the early 90's, West Coast Rap topped the charts. Early 90's East Coast Rap was conscious Native-Tongues Jazz Rap (i.e. ATCQ, Pete Rock & C.L. Smooth, Gang Starr, Main Source) and Afrocentric political Rap (X-Clan, Public Enemy, Brand Nubian, Intelligent Hoodlum). The whole East Coast resurgence of the mid 90's was influenced by West Coast Gangsta Rap. The only real notable hardcore rappers who talked about gangsta shyt on the East Coast before about 93' were Schooly D in the early 80's, KRS-One on one album
Criminal Minded and Kool G. Rap. And yes, all of the albums you listed delve into subject matter almost strictly revolving around the underworld of ghetto gangsterism and crime except for the
Main Ingredient. The East Coast invented Hip Hop as an alternative activity to help stop the violence that was rampant in the streets of the Bronx in the 70's and early 80's. West Coast Rap was always more of an uncensored ghetto documentary. East Coast rappers didn't even curse in the 80's and early 90's.
