Pros
Pro Customization options
There are so many ways to customize to your liking, such as, brightness/contrast, sepia/grayscale, font choices, and my favorite "Experimental theme engine" setting that analyzes each site to give the best dark mode option.
Pro Works with YouTube videos, and most other sites too
A number of "YouTube downloaders" will only work with YouTube. Others (maybe the same ones!) no longer work with YouTube after changes were made in the YouTube interface and encryption. But VDH just keeps on working!
Pro Rarely fails to "see" and download video and audio streams
Many similar tools will often fail to download certain video formats or DRM protected streams. VDH fails to download 5% or less of video streams.
Pro Conversion license is very affordable ($15 lifetime license)
Pro Automatic conversion rules are very handy
Cons
Con Very slow
Con Doesn't work on all websites
