If you are fine with a peep it makes no sense not to keep shooting with one. I never liked the small sight picture with a peep and now my old eyes could not deal with a it.
If you want to shoot peepless I am a huge fan of the Perry's No Peep for hunting. It is simple to set up, intuitive to use and built like a tank. I cannot recommend it enough plus the owner is a great guy to deal with.
I have not tried the IQ but have tried similar sights where you have to glance up to a sighting circle then back down at your pins. With the Perry's No Peep all you have to do is look at your pins and you instantly see if you are canting the bow or torquing your bow hand. I just don't see how there could be a better no peep sight.
