I wanna say yes and no, it's kinda weird for me.
I find the entire aspect really interesting, that there are parts of the games that go beyond having a type advantage against an NPC whose team remains pretty much the same throughout the course of the game. I like seeing how changing a hold item and a few stats and moves makes a Pokémon entirely different to use and counter. Plus the fact that you can't revive/heal any Pokémon in need makes it more challenging, which makes it more interesting for me.
I'm not like, obsessive over it though, probably because I'm still really new to the whole thing. I care about having good IVs/natures and the right EV spreads, but just because a Pokémon doesn't have 31 across the board doesn't mean it's useless to me either. I also find EV training a little boring after too long, probably because I don't have any power items (yet) to expedite the process, so I rely on my Exp. Share and Macho Brace to pull their own weight which only goes so far.
If they took the competitive aspect out somehow (not sure how they would), I'd probably run out of things to do really quickly. It's the only reason I keep playing after I beat the Elite Four.
Oh, I've never really played on Shoddy (not sure if it's working correctly yet), and honestly I'm kinda shy when it comes to things like that. >_>
