One small difference....the SAS guys did not wear suicide vests and had every ambition of having a Pint or two after the raid.
I think that's largely irrelevent when set against the skills required to infiltrate a heavily defended installation and successfully render an entire FJ sqn non-operational. There have been many operations conducted by 'traditional' military forces over the years that in theory were one way trips - just ask any of the Cold War era pilots with targets in Russia. The limited prospects for return wouldn't have stopped us executing those missions.
As for 70 virgins - really? They must be onto 'sloppy seconds' by now?
