I guess experiences vary. My laptop is a quite old system so the problems are more apparent but as I said they exist in modern hardware too. I'll try to record tomorrow to show what I mean.

I never had my laptop reboot on its own neither thankfully. Although forgot to mention the overhead windows has for seemingly no benefit. It constantly used 20% ish of the laptop's cpu. And search indexer claiming external drives as its own and preventing ejection..

I have a worstation Zbook, not newest but very good specs. The problem with Windows is it is inconsistent. Sometimes things go well, and sometimes like OP mentioned I open a folder in file explorer and i get a white window while Windows figures out if it wants to show me files in that folder.

Sometimes I unzip an archive and no folder or files showup, even after a refresh, so I try the unzip again and it tells me thr files/folder already exists LOL.

When I add a network share to a mapped drive letter in the command prompt it shows up fine in the command line for use, but does not update network mapped drives in File Explorer. Last Year this worked 100% fine...so some update killed whatever update process should happen.

I could go on, but I think you would get bored. And before people say "it must be your machine" I also run another brand new workstation managed by a corporation. Many weird issues there also.

Here are depictions of (in order):
Resized window going white before it's contents resize
Window tiling suggestions only animating right side of the screen
Windows rendering one by one after super+d
The kdeconnect stuttering I mentioned happening with passmark. Not sure if it's visible in the video, but was very noticeable in person and also made the display brightness fluctuate. (This is probably a problem specific to my install/configuration as it didn't used to happen in the previous install)
