I used it to run Pro/Engineer (now called Creo) in the mid-90s. Prior to that, it only ran on Unix workstations from Sun, SGI, etc. I also had Macs for personal stuff at the time. I remember NT being remarkably stable in comparison to regular Windows, and MacOS of the time. It would run for weeks and weeks without crashing or rebooting. It wasn't sexy, but it worked.
