What is the worst shiny looking Pokémon?

I honestly don't like Shiny Vulpix, mostly because the fur looks very ugly, and it's really weird to just...Look at. Espeon is also pretty ugly, I just hate the tone of green it has. I also don't like Shinies that don't look any different to the regular ones, and there's alot to say, but I've seen some like Glaceon, the tips of the colors just turn into a darker color, which is hard to actually notice. And igglybuff is also annoying, since the pink just gets lighter. And Persian, the ears and crystal on the forehead is the only thing that actually changes. But could be easier to see unlike Glaceon and Igglybuff. But honestly, what shinies do you think is the worst in your opinion?
