My comment "better" was that the Mk.3A Sea Kings have the facility to go from on top the target in to a pattern to the auto-hover, rather than having to be radar guided (or use a TANS Teardrop tachnique) to a position so that a transition down can be made into wind. The Mk.3A and the S-61's LN450 can both do this.
Hope that answers your question?
