For me, it's 100% yes. I've always adored having shiny Pokemon and it's so much more exciting when you happen to stumble across one randomly. But, I did used to spend long periods of time searching for shiny Pokemon. In most cases, they look so much nicer than the original versions of the sprites and the fact that they're so rare makes it more prestigious to have them. There are times where I've been doing a challenge and I completely changed it purely because I found a shiny.
