I’m going to be entirely honest, this is a virtually impossible macroeconomic question to answer with any concrete number that doesn’t rely inherently on vibes.

What do we consider part of the economy? Consumer? Infrastructure? Military? Utilities? What constitutes “planned”? Very little of the consumer market in China is truly planned, and are we counting extremely heavy oversight and regulation, or only direct control?

Also the number is actually “decreasing” in China, not because capitalists are winning, but so many private businesses are opening and succeeding each year.

North Korea is a black sheep siege economy, plus we have little to no economic data to base any answers off. The Russian economy is nearly entirely subsidized by oil and gas production which you could say is “planned”, because the same oil oligarchs also run the government. I don’t want to touch the US economy with a ten foot pole, as dissecting the largest/second largest economy on the globe is a terrifying prospect.
