Having a car will provide a lot of flexibility. I like the idea of being able to stop to take photographs, in particular. And, you are not tied to a schedule. However, you may find that public transport with one of the passes suggested will be convenient for a lot of your local travel that would normally be done by car, because you can look at the scenery instead of driving. ;-)
Public transport is quite frequent and has many routes. There is a dense network. Of course, you can't drive a car to many places, such as up the mountains, and there a quite a few car-free villages such as Wengen. In cities like Thun, finding parking may cause you to drive around a bit. We never had trouble in Interlaken, but it can get busy in the summer.
When we have stayed in the interior towns in the Lauterbrunnen valley and on the mountains...such as Wengen, we have parked our car in the large garage in Lauterbrunnen and not used it for several days.
