No way to have the DMM version translated, though there are some guides in English for it.

Personally I play the Nutaku version. While it's true that its behind you get a chance to do all the original events and get the units and eventually (in a few years or so ) we will reach the current DMM version.

The Nutaku version is mostly ok. Events are coming pretty stable now, there are a few issues (you'll see some people whine about those a ton ) but imo its ok.
