Aloha!
Well, my first tier continues to migrate, as it always has done since I started shaving with Williams Mug soap decades ago. Currently I'm putting Speik Cream and Tabac Soap right among my top tiers. The Germans (IMO) have it figured out. Both of these rival my most expensive soaps and creams with regard to lather, protection, and of course scent. I have the complete line of products from both, and I can't say that I enjoy any soap/cream BETTER than these two German products.
I have also been highly enjoying Ariana and Evans, especially "Asian Plum". Their new Kaizen base is amazing, and the fragrances from this company are astounding. Definitely a top tier soap company in my Den.
I'm also migrating more and more to Truefitt and Hill. Their "West Indian Limes" is very pleasant is currently on my top shelf. Their tub of cream is an amazing product that yields a silky smooth shave every time. The very first time I used this cream I forgot it was a cream in a soap tub. I loaded the brush like it was going to be my last shave forever. I had enough cream in that brush for 10 shaves.
Out of left field there is one more soap that has gained access to my top tier shelf. That's the limited production run of "Governor's Island" from Talbot Shaving. They made a very low production run of this soap for Pasteur's Pharmacy in NYC. I could only buy ONE tub because that was the limit for such a low production run, but I wish I could have purchased a dozen. It's my favorite scent of all time, and the lather and protection it provides are absolutely superior. I contacted Talbot and told him how much I loved the product. I doubt he'll do another run because it was supposed to be "exclusive". If he does run another production, I'll be first in line.
