In my opinion the barrel mounted swivel is far more robust than some of the forend mounted ones.
In flat, easy going hunting areas this might not count for much, but in more difficult terrain things can be very different.
When climbing in steep country, crossing rivers etc where a slip or fall is likely, you often sling the rifle across your chest to be able to keep both hands free. This sometimes puts considerable load on the swivels and often I've had QD forend swivels work loose in the wood and start to rotate.
With a barrel mounted set up this cannot happen.
For any rifle to be used in challenging country I'd prefer to have the barrel mount front swivel regardless of recoil or barrel carry height.
