Google's definitely better, but let's not pretend that the file manager experience is equivalent to any of the desktop OSs.

I've been using Xplore on Android for ages. It's an amazing file manager.

With it's SSH, SMB, and Wifi-Filetransfer it has so far outclasses most desktop filemanagers that I have tried.

It might not be stock, but it's easy to get from the app store.

It seems that the default desktop file managers haven't received a lot of developer love in the past two decades either.

Android has good third party file managers though, like Solid Explorer.
