My understanding is that much research does, in fact, show that it's more satisfying. Kids enjoy food more (eg, are less picky) when they've contributed to making it. People tend to value their own, lower-quality artwork than someone else's higher-quality work because they themselves put the effort into making it (and have some emotional connection to it).

I want to say I first heard of this finding through Jonathan Haidt or Daniel Gilbert, but a cursory search doesn't bring up the study.
