The WataMote (It's Not My Fault I'm Not Popular) anime had a vibe that was more sympathetic to the main character. In the manga, it felt more like she deserved her fate, which was kind of grim.
I'd rank the manga for Defragments slightly ahead. Being a bit more concise actually made it more funny, plus Takao's boobs were more impactful.
You can't replicate that with static images.
Yuru Yuri is much better in animated form. The voice work, especially for Kyoko and Yui, really makes the characters come alive.
I liked the Skip Beat anime better because, at first, the Skip Beat manga is kind of cluttered and unpolished. The mangaka's work gets a lot better but I remember thinking that it was hard to follow.
Same with Shirayuki-hime. I dropped it after the first chapter because it seemed amateurish. The anime felt like a superior and more professional product.
Chihayafuru is a great example of an anime that's amazing, not because it's better than the manga, but because it does a great job bringing to life the action parts of the manga. I honestly love them both equally because they do different things well.
