Better than anything that came after
In many ways Windows 3.1/3.11 was better than anything that came afterwards from Microsoft.
If copying multiple files with 3.1;s File Manager there was a problem, such the a source or destination files was open, it would warn you about it and allow you to continue copying the rest of the files. Win95 File Manager and all that follow, just abort the entire process with half the files copied, forcing you to find the culprit, exclude it, and copy everything again.
If you had an iconised application window in 3.1 would allow you to drop a file on top it, and the file would be loaded in to that window. In Win95 and later you can't drop files on to the taskbar icons, you get an error box telling to go through the utterly ridiculous palather of hovering over the icon mid drag, waiting an age for the window to deiconise, then dropping the file on to it - why for fucks sake?
Such is progress when it comes to the worlds worst operating system.
