This is "better" version from Manga Studio Debut 4. It has more features and is much more professional. Although the price is quite steep if you're serious about art and creating authentic looking manga this is the best tool. Even if its not for a manga, the built in patterns and different pens and brushes is worth the price. It's better than Photoshop because its not at all complicated to understand, but more complicated than Open Canvas, Corel Painter and SAI. However if you can speak Japanese or is willing to wait for the English version - I recommend IllustStudio. From the same creators but with more tools and 3D imaging added. It's like SAI mixed with Photoshop and Poser. It's a lot less expensive BUT it is geared more towards regular artists rather than mangakas.
