@CommanderPigg; why cross out AshxShooti? AshxShooti is hawt :3
The original series really only had a handful of ships like Pokeshipping, Rocketshipping and Palletshipping going for it (in comparison to later sagas where there were much more ships to choose from), but considering I love all three of those I had a lot of fun with it.
AG was really awesome with all the contest drama. So many great interactions between all the characters. Contestshipping, Tensionshipping, and Cookieshipping were all really fun to ship and I still ship them to this day. There was just so much friction and tension between all the coordinators and I absolutely loved it.
DP had a lot of great opportunities too. The fun ships didn't come from the contests this time (at least for me) but from the rivals. Paul, Barry, Conway, characters like Lyra and Khoury, just so many choices and all so much fun.
Best Wishes, oh man, don't even get me started. There are soooo many ships here that I absolutely love. Cilan/Ash, Cilan/Iris, Ash/Iris, Cilan/Burgundy, Iris/Georgia, Burgundy/Georgia, Ash/Bianca, Cilan/Bianca, Ash/Trip, Bianca/Georgia, Ash/Stephan, and even more besides that. I have waaay too much fun with all these ships and I just love watching things like the Don tournaments because even if the battles aren't exactly amazing, the number one reason I watch this show is for the interactions, and the interactions and shipping potential between all these characters is just fucking awesome.
So while I love shipping in all of them, I think Best Wishes wins for me.
