Personally, I don't like any of the large bits in a facial bar. Body yes, but my face is too sensitive for all the scrubbiness. I adore activated charcoal in my face soap though. I've been developing it for about a year and that's the additive I've like the most (as well as my test dummies, AKA beloved family members!). In a body bar I like poppy seeds, ground nuts, coffee, tea, etc. It just depends on the body part you're cleaning.
I think making an individual bar or two of each additive is a great idea. Use the sea salt, fennel, dill, poppy, etc in a portion of a large batch and see what you and your family\friends think of each. Testing is the best way to decide what you think of each additive.
