I believe it is, but everyone's eyes are different.
Case in point, when I was looking for the lastest rifle scope I purchased for my main rifle. I literally purchased 19 rifle scopes ranging from a price tag of $350 to $1200. I compared a lot of the main brands and models.....Leopold, Vortex, Swarovski, Stiner, Zeiss, Nikon, Cabelas, Bushnell, and maybe even one or two I forgot. I made myself an eye chart and posted it at 100 and 500 yds in the field behind my house. Initially I compared the scopes 1x1 and would put the "loser" back in the box to be returned. Eventually, I narrowed my selection to Swarovski, Leopold, and a Cabelas model. I ended up going with the $600 Cabelas version because I never could tell a difference between that and the $1000+/- Leopold or Swarovski. However, my brother and a buddy swore up and down the Swarovski was better for them.
