I don't know what SR is but.. to me? It makes it more special if the shiny was truly random. Like winnng the lottery! Some people shiny hunt but I dunno why.. I guess I just never bothered.
I remember I was playing Gold on my gameboy pocket, and I was doing the bug catching game, and caught a venonat while not really paying attention (was also watching tv,) and I was angry afterwards that I couldn't get a scyther or pinsir.
Then when I put it on my bro's gameboy colour, I spazzed out that it had sparkles and was a different colour; I remember it so clearly!! Was in the spare room where the N64 was hooked up and I just flipped and ran to show my brother hahaha!
