Agreed. I think this is the best update we've had the last couple of years. So much stuff behind the curtains being added or updated, which is excellent. It is very remniscent of Snow Leopard, so as long as it ends up being extremely stable, it may become the next go-to installation by default.
Metal appear to have been pushed a lot forward, which is excellent, and it may now be ready as the main driver for graphical stuff in the OS, so the half-baked OpenGL we have now can go for good. Add on top support for eGPUs, VR, AR, h.265 and APFS, and you actually end with a lot of leading edge stuff in this release!
