There are really only three kinds of tool for saving a YouTube video: a browser-based downloader, a command-line program, and a desktop app with a window and buttons. People argue about which is best as if there is one answer. There is not. They suit different people. So I put one of each through the same three tasks and watched where each pulled ahead.
The tasks: save a single clip fast, grab a video in a specific resolution, and do it on a borrowed computer where I could install nothing.

The Contestants
In the browser corner, the download youtube video tool from dlyt. In the command-line corner, yt-dlp, the power user favourite. In the desktop corner, a typical GUI app of the Open Video Downloader sort. All three can save a YouTube video. How they get there is where they split.
Round one: Save One Clip, Fast
The browser tool won this outright. Paste, pick quality, download, done in well under a minute with nothing to set up. yt-dlp is faster once it is installed and you know the flags, but “once installed and you know the flags” is doing heavy lifting in that sentence. The desktop app sat in the middle, quick to use but only after a download and an install you do once.
Round Two: A Specific Resolution
All three can do it, but the experience differs. yt-dlp gives you total control if you are comfortable reading format codes off a list in a terminal. The desktop app exposes resolution in a dropdown, clear enough. The browser tool put the resolution choice right there before the download, no codes, no menus to hunt through. For most people, the browser approach hits the sweet spot of control without homework.
Round Three: The Borrowed Computer
This round decided my overall pick. On a machine where I could install nothing, the command-line tool and the desktop app were both out of the running on principle. The browser tool did not care. It ran in a tab and behaved exactly as it does on my own machine. If you ever download on devices that are not yours, this is the deciding factor.
The Scorecard
| Need | Browser (dlyt) | Command line (yt-dlp) | Desktop app |
|---|---|---|---|
| Save one clip fast | best | fast after setup | quick after install |
| Pick a resolution | easy, up front | total control, technical | dropdown |
| No install allowed | works | cannot run | cannot run |
| Batch hundreds | one at a time | unbeatable | strong |
Ranked for the everyday person who saves the occasional video: the browser tool first, for working instantly anywhere with no setup, the desktop app second for a friendly window once installed, and yt-dlp third only because its power comes with a learning curve most people will not climb. Flip that ranking entirely if you are archiving thousands of videos on a schedule, where yt-dlp is in a class of its own.
What None of Them Changes
Whichever you pick, two limits hold. The file never beats the source, so a low-quality upload stays low quality. And none of the three reaches a private or region-locked video, despite what some sites promise. Those are properties of the video, not the tool.
So Which Should You Use
Match the tool to the person. If you live in a terminal and batch huge libraries, yt-dlp. If you want a permanent app with a window, the desktop route. If you want to paste a link and have a file in fifteen seconds, on any computer, with nothing installed, the browser tool is hard to beat. For how most people actually use YouTube, that last description is the common case, and it is why the browser tool took my overall win. Save only what you have the right to keep, and pick the corner that fits you.
