I prefer full-odds hunting these days. Although I've had major luck MMing Shinies in the 3DS games, it got to the point that they felt too mechanical and made nearly all of them lose their personal value to me. I can't help but wonder, had I not been using a Shiny-boosting method, if any of those still would've been Shiny and feel more special to me today. Now they're just sitting in a box in Moon and will probably be traded-off if I ever find full-odds versions.
There are still some non-full-odds Shinies I'm quite attached to though: my Shiny Dunsparce (chained in Pearl), Shiny Glaceon (MM'd in Black 2), and Shiny Persian (non-MM'd egg post-Shiny Charm in Black 2). Likewise, there are some of my full-odds Shinies that I haven't really bonded with.
