I did the Universal VIP tour experience, which included the front of the line pass. I wouldn't spend $119 for the ticket/pass, but I did pay $200 for the VIP tour - which was a great value (and we got back doored into attractions for half the tour, before going backstage). THAT was well worth it, I just finished putting pics up. But I am not enamored with the park itself really, I would probably just do the VIP tour again. I prefer walking around movie set areas!
The people I spoke with who did have the regular front of the line passes did find them worth it, especially since it was so busy. I used my front of the line pass just for Back to the Future, I went home after that (the tour was over 6 hours).
