I find the #1 to be imprecise to my eyes/brain past about 150 yards. I know that technically it is not, but my brain didn't want to use it past that, especially on moving targets.
The #4 of some type is still the best IMO, even if it is spread too wide and is too thin in the center. It still really pulls the eye to where it needs to be.
I actually think that the Zeiss #20 is about perfect.
