The scene:

In 1998 the Good Friday agreement puts an end to the sectarian violence in the north of Ireland (Yeah!) Bill Clinton denies having sexual relations with Monica Lewinsky, only to later admit that he did. 

The Version:

Metallica's version was off their cover album Garage Inc., which won a Grammy award for Best Hard Rock Performance. It's heavier than the original, with an actual bass featuring very prominently and distorted guitars replacing the acoustic rhythm guitar. James Hetfield's characteristic snarl maybe feels detached when compared to the original but fits the band's style better.

Conclusion:

Since I'm Irish, I can't help but like the Thin Lizzy version more, but I recognize that the Metallica version obviously has its fans. The version also kind of cemented Thin Lizzy's reputation as a major influence on modern hard rock and metal despite not having had any real huge commercial success.
