I believe HQ just gives you double experience, just like all turn-ins. Now, if only the exp gains weren't trivial... double nearly nothing is still nearly nothing. I used to try to give mats to lower level crafters so they could get experience from the turn-ins, but then I looked at the numbers, and there's just no reason to bother.
Lower-level crafters will get a lot more experience than high-level crafters. Where as most turn ins show me anything from a few hundred to a few thousand exp (lol) my FC mates report exp gains of 10-20k which is still small but 10 times the amount I see as a reward, so it has something to do with craft vs recipe levels for sure. Also my results are the same in terms of NQ vs HQ. I've honestly had more luck with NQ stuff giving good quality gains which is quite sad. I've also never seen extra quality from HQ vs NQ, but I have not done a significant amount of testing on it because well, there is no auto-HQ quick synth =P
