Question How Do the Swiss Half Fare Card and Bernese Oberland Pass Work Together?

Hi All, After much research, I was thinking of buying the Swiss Half Fare Card for our trip until I stumbled upon the Bernese Oberland Pass. Now I'm a bit confused about how these two work together. Does the Bernese Oberland Pass offer better value if we're planning to stay mostly in that region? Or does the Half Fare Card still make sense for broader travel? I'd appreciate any insights or experiences you have with combining these two passes.
