Sekai Project already has enough glaring flaws and MangaGamer doesn't bring over the best stuff from the companies they decide to work with. Honestly, the best option at this point in time is to learn Japanese if you have the time and motivation to. It's not looking amazing with localisations. Sekai Project brought over quite a few big ones, but they're starting to become more and more hated every time they use Kickstarters and JAST is barely releasing anything nowadays.
