I've looked through the Ares 20-60x85. Good clarity and quality for the price point. If going Athlon in the 66-70oz range, also look at the Cronus. Slightly more expensive, but better than the Ares in the same weight range. Look for sales, sometimes the Athlon scopes will go on nice discounts throughout the year.
I have a Athlon Talos in 20-60x80. Which isn't in the class of the Ares or Cronus as Talos is the entry level model and not UHD.....but for <$200 and 38.5 oz, I'm happy with it. Nobody is going to mistake it for a Swaro, but it's served it's purpose for me. Was able to spot an elk herd on a ridge over a mile away last year and take some photos. Picked out the bull just fine with the Talos. Also used it on some east side bear hunts. I would say the Athlon brand is decent quality for the price points they are at.
