The Saver’s Daypass is valid on any train, bus, tram, etc. in Switzerland on the booked day. It is only the Supersaver’s ticket which limits you to a specific connection. So yes, the saver’s daypass is currently the best option.
The saver’s daypass currently costs 52.- in the second and 97.- in the first class, whilst a regular point-to-point ticket (also valid on all connections) costs 73.- in the second and 125.- in the first class.
