I know it's hard to decide, but I think you've been given a lot of options by now for day 2. There's not necessarily a "best" choice, and it depends on your own preferences. The boat trip over Lake Brienz during your trip from Zurich towards Interlaken would be a good choice, and there's a whole range of mountain top visits you could do in the afternoon (see my previous post). But again, you'd best check the attraction pages and see what appeals to you personally.
