I apologize if this has been asked before but I can't find any relevant posts.

I have been lurking here for a bit and I constantly see how many users have Nutaku and DMM accounts for Aigis and how they say that the DMM side of things is better and even recommend having an account there over Nutaku. What I like to know, is it worth it? I have been playing since the tail end of the Pirate Beatrice event and have managed to get a decent team for general purposes (I tend to play slow).

Since I have been playing for so long on Nutaku, should I do Dmm as well? Will I be able to get events that I have missed? Is it worth putting extra time and effort for it so I start at the very beginning? If it helps I could also post pictures of my "collection" for you to able to assess the situation.
