Feh, so much Suiseiseki hate. I love Suiseiseki, and while I don't know if she's the MOST moe character there (in my opinion), she's certainly worthy. Any of the 8 finalists were worthy. Hell, any of the 16 bracket subgroup winners were worthy.
Overall, it was a great tournament, and kudos to 2ch for running it, and anonymous saimoe-image-maker for keeping us up informed with very nicely made images. We could always just check the Japanese site, but having it all in English, with pictures, made it a bit easier.
So anyway, yay for Suiseiseki. She was my favorite Rozen from the start (long before she became a meme). Not my "favorite character ever" but, once again, worthy.
