I bought a bunch of gun sights for my P700SA. From open sights, to reflex sights, to red dot sights, to scopes and a laser. Each have their own attributes and issues. For me the P700SA has a loopy trajectory. These PCP pistols shoot slow, so field of view is a big issue, especially at close range for pesting purposes as well as quick target acquisition. Because the pellet trajectory is slow, hold over and under is the plan of the day. Of course the higher the sight line over the barrel line, the more difficult this becomes, but the hold over and under requirement is unavoidable. This takes lots of practice to master. My point here is that in my experience there is a clear winner. and that is the reflex sight. Your target is in view from a 10' range all the way to 50 yards. Memorize your range card, know your range and practice holding low and high.
