Speick is one of my favorites, both scent (especially scent) and performance of the cream are fantastic, and AS is pretty good too. It's the cream that'll always be in my rotation, no doubt. Subjective of course, but Truefitt and Hill offers slightly better performance for me. As it often happens, this of course comes at additional cost.
Best I can describe it...It has a mild spicy/lavender scent, which is also a bit earthy. The ASB is very close, scent wise. The AS splash is similar but a bit more medicinal IMO. The AS is somewhat cooling as well, I believe it has a bit of menthol in it but if it does, it's hardly noticeable.
I use and really like all of the Speick original products. The Deo Stick is excellent too
