Hmm, when I breed, I personally keep all of them (with the ones of natures that I like). I'd check the IVs AFTER getting about a box full. Only because I find that it's much faster to check like that versus doing one at a time.
But, IVs definitely make a difference in battles. Someone who knows NOTHING about IVs versus Someone who knows stuff about IVs, and actually spends time to get good ones.
The person who knows stuff about IVs and actually spends time to get good ones will generally win; dedication leads to victory.
This is, unless the person who knows NOTHING about IVs has some great great unbeatable strategy (in which case, if they're not willing to try and get nice IVs, they're probably lazy and slapped 6 standards with no strategy together anyways)
