Ya, I guess it depends on how you hunt. If you hunt with a pack like I do I don't want to have additional shoulder straps to mess with. I already have my bino straps and adding a 3rd set is too much and uncomfortable.
For long treks, packing a rifle in a pack is the best way as far as comfort and security goes but you better not need to get off a quick shot.
Where this option works well is once you are getting close to your location or if you do need to do some stalking. Then the gun is ready for quick action but you don't have to carry all the weight and tire out your arms and shoulders. You hardly know the gun is there.
You can adjust the straps to change where it points. If you fall your gun can be in trouble in just about any position so I am not sure that is a real negative. Just don't fall and you won't have to worry about it.
The only way your crown is heading for the dirt is if you are falling on your head. Maybe I am lucky, I haven't fallen at all while hunting, let alone a fall where my head was going to be the first to impact!
It is far better than a standard sling in that regard though as it can't fly off your shoulder and land who knows where as you fall. You know right where it will be.
