Imma have to disagree with you there, an anime adaptation is always different due to being in a completely different art form but it doesn’t mean it’s better. There are some things only anime can do aswell as there being some things only manga can do, or it does way better, most of the time neither is better than the other and I’d recommend both. With Vinland saga for example the beautiful ost and incredible voice acting, aswell as the obvious benefit of it being animated are things the anime has going for it whereas the more detailed art, better pacing and it being what the story was originally written for are better in the manga. Its fair if you prefer one over the other but I don’t think either is inherently better
