My daughter has one on her Mathews, based on a recommendation from my brother, who shoots those sights on Mathews bows. My daughter and I are stick bow shooters and this was her first venture into compounds.
She used the IQ for a while and then had me disable the IQ feature by covering the display. Having come from stickbows, neither my daughter nor I see anything as being rushed when shooting game animals with a compound, as they are fairly stagnant, take your time pieces of equipment by nature of the design, in comparison to our longbows. But for shooting tight groups to hit small critters, like squirrel, the raised drop rest on my daughter's Mathews creates a bit of sensitivity to bow cant in relationship to the hand, when compared to my daughter shooting on top of her hand with her longbow. As a result, once at full draw, she now tends to take a quick glance at the sight level, which is at the bottom, to confirm her feel for the bow is correct and that it is plum, she then places her total focus on the sight pin, looking through a peep, while totally ignoring the IQ dot, which is at the top of the sight. She is very consistent with sighting a pin through a peep, and therefore saw little advantage at removing the peep and centering by aid of the IQ dot. I did, however, notice a slight advantage with using the IQ without peep during low light, in that the peep tends to reduce the available light reaching the eye. My daughter then tried the IQ when kept in combination with the peep, but this was just too much crap. So she had me plug the IQ feature so it could not be seen and she now uses just the fiber optic pins with a good peep.
Flip side, my brother is a fan of the IQ, but he uses a bare string without any peep.
Best
