Okay, you're focusing more on the ignored jewels of the season, no?
I mean, I agree with Planet With being cool, though as you said it's a shame that the final episodes went by FAST, a little rushed but overall well done. What I loved the most about Planet With was the wacky ideas and design of the aliens: A cat spaceship and a dog spaceship, c'mon!!! that's so crazy!!!
Asobi is Asobi, definitely, it's bad for the health, too much laughing caused me back pain and pain in the jaw too, and just like you said, Hanako is SO, SO, SO damn funny, OMG!!! props to the voice actress indeed. Their three personalities just meld together in one crazy way, not to mention the other supporting characters, like the girls from the shogi club or Olivia's brother, the president and vicepresident. I still laugh when I remember the vicepresident's makeup episode, that was hilarious.
And Starlight gets a prop from me due to originality. I thought it was ANOTHER idol anime but it's about stage acting combined with a bit of mahou shoujo and some complex stuff (Nana's episodes got deep). I'd liked it due to originality and good animation but it's no masterpiece either in my opinion.
I'm suprised you didn't include Island in the list, maybe you haven't watched it yet? that one REALLY went under the radar at least in my normal circle of friends despite being awesome from episode 5 onwards.
