Which subs are better to archive? DD or gg?

I just downloaded gg so I had an excuse to rewatch that episode, and there were quite a few differences.

gg good points: subbed frames/songs. Kanbaru = Junior.
bad points: Cropped video means subs overlap with picture. Calm/Phrasing?

DD good points: Sentences are phrased better, Subs don't block picture most of the time
bad points: Spelling mistakes, Kanbaru = Senior, ambiguous phrasing as to what Hitagi is "doing something" about (answer = her fear of sex). panels & songs aren't translated.

Perhaps the biggest difference is Araragi's comment after Hitagi still ends up phrasing her requests in a demanding manner.

DD: In the end, that's how you phrase it.
gg: In the end, you're still so calm.
