I will admit that I am not overly familiar with Chinese politics, but I would say that the current CCP does seem to be run rather well. If you could point me in the direction of information on the succession process that would be appreciated.

I wont call them dictator for the same reason, the President doesnt hold supreme power either

You have landed on the only systemic issue that I have with Chinese internal politics, I do not doubt that the president doesn’t hold supreme power, but the party does since opposition parties are banned. This in my mind would mean that the actual most powerful position to hold is that of chairman of the CCP, this means that irregardless of how the nation is governed, effectively it is entirely run by a small group of autocrats. The Chinese system seems to be very similar to the constitutional monarchies of the early modern period with the biggest difference being that the ruling class is not necessarily hereditary. All this is to say that I think the system is great so long as you hold similar ideals, I do not, which is why I personally don’t like it, but I cannot deny that it works.
