If the scope will be used for big game, then reliability is paramount, too much time and money goes into hunting these days for equipment failure to ruin a hunt. For punching paper or ringing steel, the less expensive options have merit if price is a determining factor.
Have owned and hunted big game with a LOT of scopes over the decades--and have had far more "field failures" with more than one brand of pretty expensive scopes than Burris Fullfield IIs.
