It's not yuri but Milky Subway this season is really great, especially in the dialogue delivery.
Yuri isn't immune from the usual anime/LN problem of "dialogue and prose written by people that don't actually talk to other people on a regular basis" but I'd really love a yuri production, anime or even a radio drama, where it isn't just two girls in the recording studio making anime voices at each other. More natural dialogue and diction.
