I like Swirlix... but it will likely go the way of Gothita or Vullaby for me and be unused because it is in the opposite version I plan on playing, and I don't care much for trading while going through the story.
That said, I will be disappointed if the shiny version isn't blue.
I'm actually very surprised that Swirlix seems to be as liked as it is considering the almost universal hatred for the Vanillite line.
I'm guessing it's because Swirlix isn't as blatant as the Vanillite line is. If they added a cardboard cone then it'd be obvious, otherwise someone who wasn't told that Swirlix is based off cotton candy would see it as just another cotton based Pokemon. Heck, someone here said that Swirlix could potentially be a poodle with alot of fur.
Combined with its not so obvious design, it's descrpition helps it more than Vanilite's: loves eating sweets to the point where its fur adopts a cotton candy like taste or smell
