Disagree. I was admining NT4.0 boxes back then and it was
1. very slow
2. constantly leaking that required weekly scheduled reboots
3. security wise it was nightmare even by that times standard
For the last point what was the golden standard back in the mid-late 90s, if we don't include mainframe/minicomputers? Was it Solaris or BSD?
Now that I think about it, I feel sad that I do not have the technical prowess to compare operating systems :/
