Are you asking /a/ what our favorite anime is? Because mine's Gurren-Lagann.
If you're trying to say Gurren-Lagann is /a/'s favorite anime, then you'd be wrong. /a/'s favorite would probably be some /a/ approved unaggressive safe title like Akagi.
Akagi is a good choice. Usually the safe-titles are mediocre, but Akagi is excellent, so it doesn't matter.
