I found Yu's story to be meh. Got to the cliffhanger and was starting to think that P4:A's story was going to be ass. Then I played Chie's next and changed my opinion. I really enjoyed her having to reface her self, her bickering with Yosuke, her joke ending, and her overall spunkiness. I even forgot her new voice actor, who I could initially not stand, for most of it. After that I did Aki's story, which was just as good as Chie's in my opinion, and watched Labrys' 2 hour long exposition/1 fight story. Not to diss on Labrys though. I actually started caring a lot more for that Brooklyn speaking robot than I thought I would. And then I returned to finish Chie's cliffhanger and ending.
Overall, I'm pretty satisfied with the story so far. It's a shame that the main character has to have the boring story (though I've heard things about Yukiko's).
