How do you know a scope is good?

What suits your eyes may not suit others .

Some may not have a problem with a reticle that is full of lines but you may .

If you can try it on your rifle then testing it for tracking ( is that the right term) to see if it goes back to zero .

Look through them and see what suits you not the other shooters out there.

Personally, when checking scope clarity I dont do it during the day with its bright sunlight and most scopes look good but in the evening when the light is fading.

Yep; would agree.
