I thought the excellent standard of GUI file management was XP's Explorer - since then it has gone downhill with:
1. additional shortcut areas (instead of just a file tree; now we've got Favourites and Libraries)
2. big display areas (that irritating bar that sits above the status bar, repeating all the data found in the status bar)
3. a keyboard navigable top-of-list bar in list view (which stops you being able to tab between tree view, address bar and main pane)
4. a file tree that doesn't by default update the main pane on the right so you can quickly have no idea where the main pane actually "is" on the hard disk, or which part of your hard disk it is displaying because the treeview on the left can have an entirely different directory highlighted
5. inconsistent placement of menubar and toolbar / jigsaw-puzzle-designed ribbon bar (does the menu bar go ABOVE the toolbar or below? What does Windows' guidelines say? Load a few Windows apps [even under Windows 10] and spot the difference: Control Panel, Explorer, Internet Explorer, MMC, Notepad, MSPaint - none of them look the same; in fact under Windows 10 see how many different folder icons you can see: about 10 - is it flat, at a jaunty angle, at the opposite jaunty angle, bright or dark yellow: see https://drive.google.com/file/d/0B7Ia9kxBln51WTF0ekVWWjZCVnc for all the inconsistent icons and window layouts, non-themable notebook pages, with the View and Search pages in that notebook being white but the general page having an older window toolkit panel on it which ignore theming)
6. an additional bar to organize/uninstall and other things that are part of system management NOT file management, with this bar being on its own bar instead of the toolbar.
In short, it's a befuddled mess.
Finder's design means you have to use the mouse for most things. Using the keyboard, try moving a file from one place to another if you're in the List view: if you've got a directory expanded and are under a child node (with that child node highlighted), where does the file get pasted?
It forces you to open loads of new windows to move files. Admittedly this is easy if you're new to computers but it's frustratingly slow compared to the Ctrl-X, Ctrl-V.
