Some people prefer the Whitetails and others prefer the Supers. It kind of depends on your body type which one fits you best.
The biggest problem with the G Series Whitetails is that the recoil blade on them can get bent. By bedding the action you minimize the chances of this happening.
They all shoot conicals well but they also do a good job with saboted bullets for those who prefer them.
If I could only own one White it would be a Super 91 or Super Safari in .451.
