I liked #793 as well, I've only seen the first 20 eps of One Piece so I hardly know 5 characters, but it was still enjoyable. It was good that they brought in another otaku member (Yurippe) as MC. I do find that this segment seems more to make fun of the members than the make actual matches
Serina was a perfect match though in this one
This segment started very promising with Dragon Ball, and I think they should do one more and make it the final one, and bring Serina in for MC too. I still think they should do Evangelion and maybe then finish the segment, or go into other fields besides anime/manga.
I've been watching a lot of old episodes lately (as to complete the whole series), and I've seen many segments that were only done once or twice that would be perfect to do again. This is of course recycling old stuff, but it doesn't matter if it old but good and entertaining. Many of these segments didn't even include 3rd gen yet, so it's new to them too.
What I also notice about the length of the episodes, the uRa Idoling!!! episodes have been getting shorter and shorter. 1-2 years ago we had 2 episodes each week of 26-50 minutes, now we have 12-20 minutes and not always 2 episodes. We had a lot of those girls talk corners there, but that doesn't happen any more, maybe due to schedule conflicts. Less effort is put in uRa Idoling!!! but just enough so fan club members don't complain
