I have Dawson’s on my P09 & S&W E series 1911. Very good sights. Also have hiviz on several of my other guns, revolvers & XD.
Fully agree w/ you on the eye catching attribute of the hiviz , big difference is in the size of the sight/ dot between the two. Arguably one may be able to achieve better accuracy with the narrower, smaller dot, especially at longer distances.
For me, I find the Dawson’s help me with hitting targets at longer distances as the front sight doesn’t cover the target as I’ve had with the hiviz. I use combat sight picture. You may have different experiences.
