I like 망가 더 많이 because it tells 당신 the whole story, and at the end of the 일 it's usually the only medium 당신 can rely on to be completely "canon" (unless of course it was a novel series 또는 something similar first). Also when 당신 read instead of watch, 당신 can control the pace at which 당신 enjoy the story.
It varies. It's awesome to see your fave characters off the page and animated, but 아니메 also often have to leave out details 또는 completely alter storylines that make it worse. If I have a 망가 I love, I want nothing 더 많이 than to see it animated.
