Elfien lied, just really well done artsy stuff. It didn't really match the tone of the show at all, but was still the striking thing that got me to watch the series when it first came out in dub a long, long, long time ago. Back when Anime channels were a thing in merry old England.

If I had to pick one off the top, it'd be "Dreamriser", also known as the OP for Girls und Panzer. The show itself was a masterpiece, and the intro never fails to lift my spirits. But don't take my word for it; have a look yourself: https://www.youtube.com/watch?v=Wly8YHLNWOQ
