I'm biased because we bought an 8 day and a 15 day Swiss Travel Pass on our two prior trips. It is without question the most convenient "ticket" you could get. It may, or may not, be cheaper than using the Half Fare card, taking advantage of Saver Day Pass or Super Saver tickets, or other promotions. We used our STP extensively each trip, often changing plans at the last minute due to weather, whim, or just because we felt like leaving early or lingering longer. No messing with online purchases via mobile devices, no looking for ticket machines. In the end, we did save money vs. a Half Fare card price. If you are comfortable traveling without a rigid itinerary and are flexible in your travel plans, you simply can't beat the STP for convenience.
But again, I'm biased. On our 15 day trip, we took 28 trains, 4 roundtrip cogwheel trains, 6 gondolas/cable cars, 10 buses/trams, and 3 boats. The year before, with our 8 day STP, we took 11 trains, 3 roundtrip cogwheel trains, no buses/trams, and 7 boats. You do have to show the STP to get the special machine readable tickets for some of the mountaintop excursions (e.g., Pilatus, Schilthorn, others) and pay a discounted price for those tickets, so it's not always ticketless travel. You will also need to buy a STP-discounted ticket to get to Wengen from Lauterbrunnen. But most of the time, you just show the STP to get on a boat, or show it to the conductor on a train, when and if they come around to check.
