I have not looked at another Leup in years since the glass on them started being hit & miss some years back on their top of the line scopes.
The Zeiss Conquest & later HD5's as of right now to me are the best low light glass in their price range - I have a Z5 5-25 I cannot tell the difference at low mag in low light trying to look over a rack here in Pa & NY - I can sit in my living room resting rifle on back of couch and switch back and forth rifles looking across my fields.
I am not familiar with the other scopes mentioned the Zeiss is truely a nice glass & customer service is top rate - the swaro glass should be as good but they are a tad bit more cost wise.
My son & I hunted together his conquest 6.5-20 was as clear as my 5-25 HD5 out in the field when the deer are being pushed down through my property by the other hopeful landowners with their $99 scopes - we have a point rule here, besides we don't hunt for meat so we want pick of the litter, low light good glass makes a huge diff. every year.
The illuminated reticle is a personal thing, i never was impressed with any I looked at, seems to me they detract when its very low light, again that may just my eyes, if i can say I am going to take him, I can see the rack well enough to see the crosshairs.
Good Luck
