Regular train tickets Basel-Wilderswil-Basel are slightly cheaper than the Swiss Transfer Ticket (here's how to calculate). If you don't mind a small price difference, the Swiss Transfer Ticket is more convenient as it allows you to arrange for it online and start traveling right after your arrival in Basel, without having to buy tickets first.
If you want to use local public transportation, the 3 day Hiking and Sledging Pass is a good choice. It's only valid in the Jungfrau region, but if that's your main focus that's fine. If you like to explore a somewhat larger area, the Swiss Transfer Ticket Combi could be an alternative.
If you order a Hiking and Sledging Pass online, you can either have it sent by mail for CHF 5.- or pick it up for free at a local railway station. You can purchase this pass on the spot as well.
