Overall, is that average sub Saharan African closer to the average European or the average East Asian? The PCA maps I’m looking at seem to conflict here.

euros only have neanderthal while asians have different levels of denisovan admixure on top
so they're arguably probably further

Blacks are closer related to Asians, Europeans have gone through far more genetic bottle necking and share a common ancestor with asians from the maternal side thats a Eurasian Neanderthal. Europeans evolved from not just neanderthal but sub species of neanderthals mixing only from the maternal side, with ancient extinct neolithic making up the paternal side, then throw in longer genetic isolation in harsher conditions.

They're a 2D representation of a 3D vector, of course you may get different representations.
Overall, Eurasians are closer to eachother than to SSA due to other hominid admix, and SSA themselves exhibit a great genetic variety. But of the Eurasians, Europeans are closer to SSA.

the thing you posted isn't a PCA, judging by the labeled axes.

This chart needs chimps and other apes included for context.
