4ch/a/ isn't THAT bad, tohno-chan and samachan are okayish, but I'm sure you know that already. Honestly, the quality that /a/ can maintain with the volume of posts it receives is kind of impressive, if only because it doesn't discriminate against lolicon (as much) and other hardcore fan stuff. What you might be looking for is one of those kitschy early web 2.0 forums, like AnimeSuki (yes, I know) or the like. https://ralee.org/ is also interesting.
