IMO GUIs are always faster when it's something you've never used before, or use very infrequently.
CLI is better if you're used to the task you're doing, or automating things. But for infrequent tasks looking up the commands (or looking at old notes to find it) is very slow and rather annoying.
Moving files across several subfolder levels tends to be much faster on a GUI. Finding files is usually much faster via CLI, even when you have to look up again how to use the find command of your choice
The more you use the commands the more you remember them. I got good at the CLI by forcing myself to use it for things I would normally do in a GUI. Now everyone thinks I’m a wizard which I won’t discourage
Everything is so fast because it uses the index built into NTFS to find files by filename quickly, and NTFS is the definitive file system on Windows so it works everywhere.
On Linux, there isn't really an index built into the filesystem - some might have that, but I don't know about it. That said, plocate is a common tool that uses its own index. You have to update the database when files change (you'll probably have a job doing that daily), but searching the index is very fast.
I usually just make a bat or py script to move and create specific files to specific folders.
I only do this because I'm lazy and numbering, renaming and creating folders is a drag and can be easily automated, but just copy/paste or cut/paste is faster in GUI, especially with alt tab and the new tab file system on windows.
Your filesystem must be monstrously huge if it's actually perceptibly slow. I also get tired of typing in long filenames with a ton of special characters I have to escape.
