History

You guys are all much more well-read on communism than me, so I ask based on this quote:

As a reminder, the Sino-Soviet split occurred due to an ideological fracture in the Communist bloc whereby Mao accused the Soviets of being “revisionists” after Khrushchev’s de-Stalinization and his embrace of “peaceful coexistence” with the West.

Now that the ex-Soviet countries are pretty much all capitalist oligarchies and China is, well whatever it is but hugely successful and prosperous, is there a consensus about the Sino-Soviet split? I mean yea it sucks that it had to go down like that but can we say in general that Mao was right about that?

I know it's just an arbitrary point in time (as now) and that there were and are loads of factors at play so this is perhaps a simplistic way of framing it, but I'd love to get your thoughts on the matter. Every time I ask something of the dope-ass bear I'm blown away not just by how little I know but also that I wasn't even looking in the right direction, so if this is a stupid question I'm sure you'll let me know, lol.

EDIT: Thank you very much for your answers! Very informative.
