IMO, from the ji-hi comparison shots I would go with taka, as said before, the picture seems clearer, the translation shows no grammatical errors, and from myself watching Taka's first few KnR HD releases, the subs flow smoothly. I had no problems with a the font, even on my TV 4-5 feet away.
However, as with all information on the internet, you should take my opinion with a grain, or two, of salt, as I'm biased towards Taka, not as a member of the group, but as a fan of their NS and DBK releases, and a frequent lurker in their IRC.
