In 2015, I used the Bernese Oberland Pass for several different trips based on Interlaken.
The Tell Pass covers a somewhat different area.
I found Interlaken to be a pleasant place but it was VERY popular with tourists from China and India and there was a lot of "hustle and bustle" in the local streets.
I agree another, quieter, place could be a better base. But Interlaken is VERY central. Note there are two separate stations, East and West. There is also a local bus that connects with trains at Wilderswil.
Enjoy your travels.
