I like the duck fat ones a lot. I am intrigued by his duck fat and tallow base, that one should ROCK.
I am finding that as I "mature" in this hobby I am most interested in finding soaps that offer unique lather. I also enjoy the complex scent creations but most soaps are too weakly scented for me so the scent becomes less relevant. Grooming Department has some unique and complex scents and most I have tried are either strong enough or complex enough to stand out.
Grooming Department fills a really unique place in the artisan soap world. Rather than offer just one or two bases, he offers several exotic bases. Even if you can resist buying soap based on scent descriptions you just HAVE to try the different exotic bases. He gets a bit of bad mouthing for not having soap in stock but I think his unique niche will keep people coming back.
