It was a wonderful operating system. It provided consumer desktop essentials (Plug & Play, DirectX 7, ACPI power management, Windows Driver Model (WDM), and support for consumer I/O interfaces like USB and Firewire) alongside a modernized UI, all running atop the NT kernel. I was extremely lucky to receive a free copy of Windows 2000 Pro as a student, because I rode that horse for years.
Then Microsoft added a green start button and dark blue backgrounds and packaged Win2k for home users as Windows XP.
It's been 20+ years so it's possible I had it wrong then, or remember it wrong now.
You would often get audio buffer underuns on the startup sound, if enabled, especially if you had auto login.
Windows ME on the other hand...
Probably very few people switched from Windows 98 to Windows 2000. That wasn't considered an upgrade path. That was installing a different operating system.
Technically Windows ME existed, I guess.
Other people ran Windows XP, but Cutler was still in charge of Server 2003 before moving on to special projects like creating 64 bit Windows and Microsoft Azure.
His attitude towards the eradication of known bugs really led to Windows feeling rock solid, with the exception of driver bugs (being the leading cause of blue screens).
