What has become great? E.g. has NeXT / macOS graphics system become great? (Yes, I dislike macOS for its lack of customizability and being opinionated. It may be great for someone, but not for me.)
For toolkit consistency I think macos is one of the best.
consistency = 1/customizability and I agree with you there, especially annoying for folks who know their way around a computer. For 3d acceleration windows seems to have the most advanced and high performance graphics that is in wide use.
