At the time, it was pretty iconic.
It's really hard to consider the best, like I was saying. Any time you look at older videos, they're all kind of bland, and anything new has big CG effects even if the song is totally blah.
They did a ton of production video stuff in the 80's, but it's all that same sort of MTV thing. The video you posted was so pre-cg that they were wearing monster costumes
Pretty good song, don't get me wrong, but nowhere near the best.
