I often hear hibernation is one of the great Mac Os Features. For my part, I decided years ago that cold booting windows works much faster than hibernating it.

I will not start to count the seconds and fight which OS boots faster, but it is certainly much faster than it was in the nineties. Boot times are certainly one thing where modern computers have significantly improved. Everyone who compares an instant on 8-bit is oversimplifying things. Try booting to ie. GEOS on one of those.
