This is only partially true. In G/S/C (Pokémon Gold/Silver/Crystal), Shinies were only found with set IVs, meaning that Shiny Pokémon could only have a few possible sets of IVs. I don't think they were necessarily better, either, but my memory is off on that.My friend says that their stats are better than regular ones but I'm not sure if that's actually so.
Yeah I've got 2 of those things. One from Sun and Moon Wondertrade, and one in ORAS waiting to be sent through Pokebank. Anyways, I guess I just like shinies because of how rare they are (save for Gyarados) and the feeling of finding one (especially in Sun and Moon) after hours of chaining is a good feeling.Checked out almost every shiny you mentioned and I can't say that I like them to much.
I got a number of shinies in X/Y because I was given a shiny 6IV jp Ditto from some random japanese guy online. I'm about 99% sure it's a hacked one but since it got through the trade online there's still this small chance it's actually legit.
With that I started getting shinies quite often. But still not a lot of luck when it came to IV's :/
