This was a tough vote between Pokémon Crono by Dante and Pokémon DarkBlue by Areku... Both hacks have the exact aspects that I like in a hack; and that's a great storyline, creative sprites and ideas, decent scripting and very impressive graphics, which balance out the gameplay and amusement of the games immensely.
I'm very sorry to Pokémon Moonshine and Ninja Caterpie... Nothing stands out to me with the hack. Hopefully, you'll try to improve on the hack and make it better for the next time.
Now, my vote has to go to Pokémon Darkblue, and I really do hope that Areku wins. I just wish both of the hacks were able to win, but I guess that that'll never happen. DarkBlue is, in my opinion, very, VERY close to Crono, but I favor it for some reason. Good luck!
