Before blaming the rib, pattern the gun and see where it is shooting in comparison to a gun you shoot well.

I suspect the role of the rib is less important than the stock fit overall, the choking, the balance, etc.

As for the swamped versus other rib types, for some it makes a difference in shooting (probably very few) or aesthetically (many more). I do not find them of any particular negative or positive note. That said I no longer own any guns with one, but that is taste, not function.
