i personally really like the 12x scope and the 15x scope for snipers.
most others are ok for AR or SMGs. dont ever scope in with my smg though. only really scope in with my sniper, or with my assault rifle.
all other scopes other than the two i mentioned are pretty hit and miss though. I'm not too picky as long as it isn't a sniper. the sniper scopes are classic. what else would you want?
i personally always hated customizable scopes. CoD took it too far in my opinion, who really wants a smiley face for the reticle of a scope? i mean really?
I generally like to use the 8x scope on my first wave m1a, I just hate the circle sight. I'm not asking for smilies and stuff, I always hated those on CoD. I would just like to use to same reticle as the 15x scope. Same thing for the 12x, I tend to use that on assault rifles in place of a marksman rifle, but I'm just not a fan of the reticle.
