MAL could do with an image overhaul tbh, even though I'm an avid user of the site I'm not a big fan of the layout - a bit dull with no decorations. Nevertheless I prefer MAl over Anime-Planet because I think it has a more active community, the main forums and anime specific /episode forums are excellent, individual user profiles are also presented a lot better there. To add to that, I also think that the anime profiles are presented better too, with an excellent selection and placement of statistics and tags.
