I think in that respect it is down to individual choice and preferences. Personally I really don't like leupold scopes for field target although many love them.
I do prefer the vortex over the sightron, I have 2 sightrons and it ranges as well as they do, I have not had a single issue with the golden eagle miss ranging targets but nor did I have this with the sightron, however i have re-parallaxed these to suit me!
I have found the golden eagle is less prone to 'white out' though which is handy!
The best advice I can give you is if you get chance to pick one up and have a look through one then do so as many people have lots of different preferences and what suits me may not suit you all
I also think the warranty that comes with the vortex is worth the extra cost!
