If we are strictly speaking ideological purity, the DPRK’s Marxism-Leninism with Juche influences is probably the least revisionist overall. China is the most “relevant,” of course, plus SWCC is legitimately a return to Marxism as compared to Maoism.

Cuba has some Capitalist roading, yes, it heavily depends on the tourist industry and said industry is decently privitized.

Ultimately though, a strong understanding of Dialectics and the Base and Superstructure is necessary when judging the impact of “Capitalist Roading.”
