I checked out Naru2u in Ottawa, ON Canada 3 years ago and it was...sad. It was small and I was expecting that, but it was inside the basement area of a Travellodge hotel, it wreaked of body odor, and was tiny, considering the price. I think it's grown slightly since then, but yeah, very disappointing. I'm quite happy with Anime North. The side is perfect for the Toronto Congress Centre, and they use the nearby hotels (literally across the street on three sides) for additional space for gaming, panels, and other activities.
I want to go to SDCC, but it sounds so...douche-y. And the tickets sell out quickly if I remember right. It almost sounds too big for its own good. I think I'd rather go to Anime Expo or Otakon.
