at the end of the day, if an RPT jet call's either PAN or MAYDAY they will get an In-Flight Emergency Response from ATC (after all, that's the whole point of the call in the first place..) In a min-fuel situation, there's not all that much ATC can do other than 'Do you want local stand-by or full emergency?'.
Sadly the real answer to that question would lie in the quality of the landing (or lack thereof..)
