I feel overall a character's thoughts are better conveyed in manga, but an anime of course is more immersive with its mesmerising animation and soundtrack.
Yet... characters are what make or break these titles. I find the pacing is better in manga as more minor characters do get featured whereas with most anime, screen time is limited for many characters. Unless it's an ongoing series or a title with multiple seasons, usually a handful of characters will get most of the spotlight.
What are your thoughts on manga vs anime in general?
