Personally my favorite ending was with the sempai, her good ending is just great and her story is very complex and more interesting than Aeka's, while Aeka's is also interesting. Nekoko's well, her story is also interesting and the ending is good as well, but out of the three it was the one that felt more 'off', I can't explain why it felt like that for me, it just does, but her ending takes the cake for the most impressive turn-around ending that I saw in a game like that.
Aeka's ending felt nice and homely, while Mizuki's (I think that this is her name) was warm, homely, surprising and funny, you got to love how he picks on his sister even then.
I liked aekas because it was the route that made my emotions come out the most. It made me feel like I had to help the character but in the other 2 routes I didnt feel that way at all but I think Nekokos was the best end even if it felt a little 'off'.
