I have both reticles on various of scopes and I will without a doubt always choose the German #4 if given a preference. My eye naturally migrates directly to the center of the scope and the top portion of the reticle doesn't block anything.
Nothing wrong with the Nikoplex, but I prefer the #4.
I just leant one of my scopes with the #4 reticle to my brother who was not familiar with it and now I can't get it back from him. Probably cost me $1000 to educate my brother.
Hope this helps you and it didn't cost me anything this time.
