Some videos are available in different resolutions.  Some have as many
as 6 or 8 different ones.  With downloadhelper, you can pick which one
you want.  I'm not sure if youtube-dl does or not.  Also, I download
videos from lots of sites.  I don't actually use youtube a lot. 

Good idea for folks that use youtube a lot tho.
