SaveFrom.net has made a name for itself over the last few years. It can do web-based downloads, but also provides software to install and a browser extension, which it pushes. It doesn't support 4K, but few helper sites do—going to a 1,440MB WebM file is an option, but it doesn't come with audio—the only format that does is 720p MP4s. Nor can you use SaveFrom.net to make an MP3. Of course, those options are in the downloadable software.

When you copy a YouTube URL (even for a playlist), click in the WinX software to launch. You start with the "analyzer," which checks all the options. This tool also tried to default to the 1,920-by-1,080 version in MP4; I picked the 4K version (3,840 by 2,160 pixels) in WebM format, a subset of the MKV format—you can rename a .webm file to a .mkv and it'll work fine. In settings there are options to default to WebM at highest res. You can set up a number of videos to back up before you even click the download button. The 4K 575.4MB file took 1 minute and 39 seconds to download, more than double that of 4K Video Downloader.
In tests, I had to make a switch from MP4 to MKV format to get my test video to download in 4K. 4KVD snagged the 579.4MB file in about 43 seconds. It defaults back to 1080p HD, so I made the same switch when downloading an Ultra High Definition (8K) playlist. If you enable the Smart Mode and its pre-sets, 4K Video Downloader can then do one-click downloads to your favorite format. If you want to download more than 25 videos at a time or subscribe to YouTube channels to instantly download the latest, that requires the $15 paid version. Playback of the MKV file via VLC Media Player was flawless.
