NT is actually a pretty good kernel. NTFS and the userland is what is shit.
NTFS is a beast of a filesystem and has been nothing but solid for 25+ years. The performance grievances ignore the warranties that NTFS offers vs many antiquated POSIX filesystems.
Userland peaked in Windows 2000
I think NTFS get a bit of crap from the OS above it adding limitations. If you read up on what NTFS allows, it is far better than what Windows and the explorer allows you to do with it.
