What do you mean with “best“? The angles, and therefore the shapes, are all wonky. Check out Japan on the equal earth projection and compare it to a map of only Japan.

Since the earth is sort of round, all projections will distort. The question is what will be distorted. The equal earth projection distorts country shapes more than the transverse Mercator does.

Those artillery numbers… I hope the Russians will run out of them soon.
