By successful I mean in maintaining relative party unity, work with the masses, and thus the masses trust in the party, and political and economic stability.
With the exception of the latter years of the Cultural Revolution, the CPC has been remarkably stable, ideologically consistent, and have maintained power and dominance over the Chinese state and economy. All of this is even more impressive given the fall of communist states in Europe and the rise of western/American unipolarity.
While similar tendencies have been found in the CPSU, the rise of figures like Khrushchev, Brezhnev, and especially Gorbachev, and of course their supporters within the party, makes the CPSU appear less stable and ideologically consistent compared to the CPC. Added onto this the fact that the CPC has a much larger and diverse membership, including the national bourgeoisie.
Rather than viewing this question through great man theory, I want to know how the structural formation and process of the CPC itself maintains stability, and how it's party structure is different from the CPSU. While both parties are founded on democratic centralism, how does this manifest differently between the two? In an interview with Marxist Paul, Hakim said the ban on factions within the CPSU, while imperative during the civil war and early years of the revolution, ultimately hurt the party. He then praised the informal factionalism of the CPC: Dengists, Maoists, liberals, etc. From the outset it would appear that such a situation of factionalism should rip the party apart, but it doesn't. Why,?
Looking at the relatively young history of communist movements and parties show that many, for material reasons, were/are unable to be stable and ideologically consistent. Again, outside factors and capitalist sabotage are of course a major contributing factor, but could there be structural elements within various parties which explain, to a certain extent, their successes or failures?
Seeing the immense progress the CPC has brought their own people and, increasingly, the people of the rest of the colonized world, means we must understand how they operate. Every party and movement will be different and adjusted to their particular circumstances and material conditions, and thus copy and pasting the CPC anywhere else will not yield positive results. However, could/should the structural basis of the CPC be applied and modified to other countries and contexts?
Just finished my meeting with PSL last week over this article, and I thought this could help with context of Deng (I am not a fan of him in regards to how his wing overthrew the other wing and enacted their own reforms at the cost of millions of poorer, rural workers forced to work for the capitalist enterprises without the safety net and protections offered by state jobs):
Note: Take this article with a grain of salt. This is an older article (2007-05-31) from the PSL that paints the Cultural Revolution in an overly positive light while omitting the corruption that occurred from Mao's wing. I apologize for my ignorance on this topic. Thank you, @muad_dibber and @qwename, for enlightening me.
What do socialists defend in China today?

At the same time I am disgusted by this event, I also wonder if it was unfortunately necessary to help China reach to its current state today. If events had played in a different way where Mao's wing would have been dominant over Liu and Deng's, could China have suffered the same fate as the USSR? In the end, the West is responsible for creating a divide between the USSR and China, hurting their relations so the West could use one enemy against the other to their advantage.
This is the second time I'm seeing the Cultural Revolution put in a good light in this post, get off your high horses you naive idealists!
The Cultural Revolution was hijacked by ultras, Lin Biao tried to assassinate Mao.
This is the Constitution of the CPC in 1969: https://fuwu.12371.cn/2014/12/24/ARTI1419387596442272.shtml, it includes this paragraph in the preamble:
Utterly disgusting.
