archive.org serves the same file you uploaded to Youtube, without 
change.

Youtube always re-encodes the video, for various reasons:
- sources are very heterogeneous
- multiple formats needed for various devices, various 
resolutions, and bandwidth adaptation
- insanely low bitrates (3000kbps for 1080p H.264 is scarce, yet 
it's not so bad with the encode Youtube does)

So while Youtube quality might be worse, the used bitrates are 
probably not the same. My opinion is that it's best to let 
Youtube serve the content for maximum reach.
