well i think KMS version is much better , that my personal opinion because it has some advance features like here you can choose colors, gms is also good but most of my friends play KMS because they do not get GMS , still KMS is better and more interesting to play. it aloso have some more features than gms as well.
Well no surprise there being that they are the original base game, and it seems in general Korean game companies in their actual native countries actually give more damns about their customers than any western game publisher.
