On the one hand, I don't think this works as well without the visuals and at least some knowledge of the anime shown. It's also a bit overly reliant on Outlaw Star footage.
On the other, it's one of the rare videos on this list to hit me with positive memories & nostalgia, and I can't downvote anything Gundam Wing related... even if it is just a two and a half second shot of Heero's face.
[FINAL NOTES: Seriously, list needs more Gundam.]
[FINAL-ER NOTES: I didn't even mention the use of Jet's voice actor. Everything about this video is nostalgia cranked up to 11; the choice of voice, the choice of anime, the timeframe this commercial is from. I don't think any nomination on the list triggered as many positive memories as this one.]
===============
I did not remember asking for more Gundam related songs, but after seeing a song explicitly getting bonus points for two and a half seconds of Gundam Wing, it kinda seems obvious why a Gundam Wing song won the R# category. ---
