Which JAV studio/label was number 1 in 2013?

[StageNinja47]

I finish posting a new thread asking if your guys have any favorite JAV Studios/Label. It got me wondering what Studio/Label do you think was number 1 in 2013?

Take into consideration:
1) quality of videos.
2) Popular videos they produce.
3) debut of popular idols.
4) Popular idols they have.
5) Your own personal preferences.

Give examples (idols, videos, with pics). and also any particular reason why you think the studio/label was number 1 in 2013.

I dunno much but just a though, it seems S1 is still the top of it due to their constant performers
but the debut idol is really make the difference, she is shion utsunomiya... her video is always the tops of most popular each months
