all of them, expect for code geass. I had rather watch yaoi anime than watch mech animes. I absolutely hate the mech genre.
Gundam Seed Gundam Seed Destiny Code Geass Overrated, shitty fanboys, edgy as fuck. The only good thing from these 3 is when people died.
Gundam seed would be on my list. When I first saw them as a kid, I liked them. I rewatched gundam seed this year, and I stopped midway. I didn't rewatch gundam seed destiny due to it. I did rewatch code geass though and I still liked it.
