I read the manga first, so I gravitate toward it more. It has more tales, it has more interactions, and the 10th anniversary additions/edits made it even better than before (notice how Kimura isn't even present in the supplementary lessons? He's kinda stuck in the original run, but at least he starts being less of a presence by the final year [poor Kaorin, though] and he's just GONE in all three of the supplementary lessons. GOOD). Animated stuff just gets seen easier over here, and AMV Hell certainly helped Azu get attention in the West, but with a memetic outlook thanks to some of its entries in those compilations...which I don't actually enjoy tbh. Anything that twists Osaka's personality is a thumbs down, in my book. But I digress. If it weren't for the anime, I wouldn't have mental voices for the cast that fit so well, and I guess Episode 19 in general....But that's all it's got for me. I have the Yen Press Omnibus hanging out in my Special Bookshelf that's on my desk - stuff I want to pick up and read or reference immediately~
