Saber Marionette What Series Had the Best Writing?

I saw J, and I like all the development of the marionettes, but I really like much more J to X. If the special episodes for each marionette were just fillers, those fillers are indeed made with an uncommon way for making fillers.
Ok, the characters were simplyfied, all was made with computers and they look more "childish". But in J to X the script is far better than in the first series (I also like a lot J!, with any doubt!). I will repeat this again, in J the marionettes learn, how to live and get a soul from Otaru, the only one who can see beings inside machines (well, not the only one as you watch the development). But in J to X, Otaru stops teaching and then the marionettes take that place. The first two episodes (those of race and the uncertain future for the marionettes), the episodes dedicated for each marionette and most of all, the last half (Xian and the ending of the series) are quite good, in fact they're excellent, very deep, and very adult.

In the end, J to X ends as Program #1, with Lime over Otaru's back. .
