You should consider the following points when buying a scope :

  • adequate magnification
  • adequate glass quality
  • an adequate reticle
  • adequate scope adjustment capability
  • sufficient recoil rating
  • great after-market service

and when you go through the considerations list and check your boxes against scopes available to you, the number of scopes for consideration is reduced to a manageable number, and the probability of coming out ahead with a scope that can meet your requirements, is better.
