I've got the vortex you speak of. I haven't seen anything that eats it til about double the price but that's not as an owner of them just using friends' really "high end" glass. Personally I think for most of us spending over a grand on optics ends up being a waste. Not that many people can really out shoot their $1000 glass. Don't get me wrong if I had endless funds and money wasn't an issue I'd get as top of the line as possible but scopes like the viper pst ate plenty clear and reliable. I've shot a 223 out to 600 yards and 308 out to close to 1000 and done well. Mind you I consider myself a novice shooter. That coupled with only a mediocre rifle makes me think out shooting the scope will take me a while.
An ideal situation is to look through a few OUtDOORs and seeing what you prefer but that's obviously tough to do
