I'll be the voice of dissent on this one... I'd take HS2 over JM all day long. The supercharger toy on HS2 is one of the best toys in pinball IMO. I've played JM a couple times and just couldn't get into it. Probably the theme although I didn't really care for the gameplay much either.
And this comes from someone who is a huge Gomez fan. LOTR and MB are my two favorite machines ever.
