I think File Explorer is excellent though I do have a few niggles with it such as the one the OP described, as well as this:
Explorer deciding that certain folders are "special": for example, if you run a command like this:
Code:
robocopy C:\users "D:\users backup" /MIR (I'll skip all the other command switches I normally use in a situation like this because they're irrelevant)
What does Explorer end up showing you on D drive? A folder labelled "Users". You have to fire up a command prompt to see the folder's actual name. IIRC the same goes for other "special" folders such as the current user's Documents folder. If someone knows how to stop this from happening (my workaround is to send it to "D:\users backup\users"), I'd very much appreciate knowing the answer! Thanks to this PITA you can easily engineer a situation whereby you open a folder and there are fifteen folders labelled 'Documents' inside.
I'm using Lubuntu and pcmanfm these days, and while it's nowhere near as awful as Finder for OS X, it's not as good as the good points of File Explorer, but it's manageable and I haven't found any hugely annoying quirks of it IIRC.
The bug in Win10 1803's Explorer bugs me to no end as well: At least 75% of the computers I've tried it on, if I get up the Properties of a user's profile folder, I get a vastly different 'size' figure (or 'size on disk') to if I open that folder and select all inside it > Properties (which gives me the correct figure).
I agree with Red Squirrel about the changes in Win8x and Win10 though, the 'folder list' pane seems to have taken a few steps back and therefore stuff is harder to find there. I'm of the opinion that Windows hit its peak with 7.
