The only way to know is to do a side by side comparison. Take your Tasco and a Nikon Buckmaster and look through one then the other yu will see a big difference in brightness and clearity. I'v never used the super high end scopes but my guns say remmington and browning not custom but right off the shelf. Not only that but a good Nikon or a Lupold come with a lifetime warranty. I have gone through 3 Tasco World class scopes on my 06 there not made to take the punnishment of the higher end scopes.Just my 2 cents Mike
