Between the two, I would pick a good Vortex. I've seen some video on the Eliminator and it looks cool, but... it seems not to let you customize your ballisitic info. From what I read, ballistic data is based off factory loads. Can't input environmental conditions such as density altitude. Also, many manufacturer's advertised bullet BC's are exaggerated. I also wonder how well the internals will hold up to repeated recoil? How long is the warranty? Don't mean to be a party pooper, but these are big questions for me.
I think you're better of with a good hand held RF like the Lieca 1600 and a scope with BDC turret. Check your drops at ranges out to 700 yds and put one of these on the elevation turrets...
