Zermat vs Jungfraujoch

Dear Mod, few questions here. really hope u can help us on this:
1) which one is the best to visit for the best Swiss experience? zermat or jungfraujoch?
2) does the swiss saver pass 2 for 1 promotional pass cover transfer from zurich to zermat/jungfraujoch?

3) I wanna fully utilise the 4 day pass, but cannot decide where to go/visit. Here's my plan so far, hope u can comment on this itinerary:

5 April - arrive in Zurich, take train (hope this includes in Swiss Saver 2 for 1 Pass) to Zermat/Jungfraujoch (stay for 2 night)

6 April - spend day in zermat/jungfraujoch

7 April - depart to lake lucerne (don't know whether is there any direct train to lucerne from zermat/jungfraujoch) - stay 1 night in lake lucerne (any budget accomodation there?)

8 April - spend day in lucerne and then depart to vienna at night

any comment/advice (with cheapest recommendation, pls)?
