I have been using scout-rigged shotguns for a number of years and now rifles.
The guns are easier to carry since you are not reaching around or over the scope.
It is somewhat like using a peep sight and somewhat like shouldering a shotgun when bird shooting since you automatically align with the scope when you shoulder the rifle, and the target is there in front of you. You don't have to think about it, the low-power of the scope is less a magnification aid as it is having the advantage of the target and crosshairs being on the same optical plane. It is actually faster to get on-target than with a conventional scope setup.
As far as range, it is more a function of the scope magnification than scope location. I like low-powered scopes for deer guns. You don't need 3x9 scopes for deer up to 200 yd. Finn Aagard wrote an article a while back that compared different scope powers and found that there in no real advantage in the field for higher magnification. I have found that there is a real chance of having the scope set at a high power when you need low power. My preferred scope is 1.5 x 4.5 for a conventional deer gun, but use 1.5 or 2 power scopes with confidence. On a varmint rifle, a standard high-powered scope is definately better than the scout. Also when determining a rifle's potential accuracy, a high powered scope is best, although my 1-1/16" group last Saturday is nothing to put down.
I guess that you have to actually try it if you get a chance. Put away your preconceptions before you try it. A generation ago, hunters were putting down scopes for the same reasons, and now you don't see many iron-sighted guns in the field anymore.
