@Creativity By Design Well Gaia has one of the best running story lines, I've always liked Tiga, and Mebius was great at being nostalgic while being outside of the traditional Ultra universe. I also really liked the imaginative Ultra Galaxy Mega Monster Battle series. And I will always have a place in my heart for the original Ultraman series that was one of my favorite childhood memories.
Tiga was the first Ultra show I actually saw in full and in Japanese. I used to own the DVDs that Funimation put out, but for some reason sold them off for 75 cents a piece. Wish I never did that.
Seven, but there are others that can compete.
Seven, no contest.
