There isn't much to say here that hasn't been mentioned in the first batch. There is more upscaled footage, especially in the later episodes, and I suspect the video was just a tad more DNR'd, but it's about the same. Some episodes come off a little softer than others, maybe for DNR or edge enhancement reasons, but it is what it is.
You will find (separate) commentaries for episodes 27, 43 (2!), 49, and 50, along with a bonus behind the scenes interview video.
One important note here is that the subs did not go through quite the same revisioning that the first box set did, because the official subs are coming, and the effort was thought to be somewhat redundant.
