>480p is especially bad with low-light of gradient-heavy videos; in that case, you need at least 720p.
YouTube's 480p option has a worse framerate and/or bitrate than the 720p option, I think.

Comparison of 480p vs. 720p: with the worse one, video compression squares/blocks are annoyingly obvious when looking at a dark room or similar.
