I haven't flown the S92 but the Puma L2 as a SAR aircraft is a long way from a good solution. All the Pumas are quite pitch unstable which makes doing decks more of a challenge. The autopilot makes the aircraft "mushy" although the SAR modes are good. The cockpit is cramped with no space for additional role equipment and the cabin would end up with a lot of folk with really bad backs. The Puma was designed to be fast in a straight line, the Sea King to be stable in the hover. A combination of the two would be ideal, I don't know if that is what the S92 is?
