All the super-automation is fine in some situations but even the VHLD (if that is what it is called) will only cope with steady state scenarios - an object in the water in any meaningful sea state will not move in a predictable and steady fashion - it will require pilot (or AHT) input to keep up. The automation is an aid but most winching jobs will still need stick and poles skills from the pilot.
The Sea King 3A has an auto-hover capability up to 200' and a HT you can trim (either on the cyclic or the HT controller) to give a relative hover and it has a very flexible TD SAR mode.
So actually the S92 is just newer and shinier
