Off hand, only ef and Honey and Clover. They're both my absolute favourite, and even though I know they're both technically flawed, I can't bring myself to agree with any of those flaws.
I never find myself complaining about Gintama or Higurashi no naku koro ni and kai. And if there are complaints usually I can't agree with them myself.
i have no complaints about the anime H20 footprints in the sand i dont know about what other people think about it but for my personal taste it was perfect
