Thanks! I'm really happy with it, and hope I can find some more of that same box in my tours of the local cigar shops. Lol funny you should mention SV's 70th considering today's SOTD...
The two are definitely different scents, but there are some similarities. The scent strength of Ethos Colonia is stronger, and it actually reminds me of Alvarez Gomez Agua de Colonia Concentrada, which is a tongue-breaker of a name for a very inexpensive cologne that you can get in a 1.3oz bottle for about $4.00. The scent of SV's 70th is both more subtle and slightly more refined.
In terms of performance and post shave Ethos has the edge in both. It is softer than SV(what soap isnt?), but it might be the thirstiest soap I've ever used and I am constantly overloading my brush. I could probably get away with about 2 swirls of a barely damp brush but I always load for about 3-4 seconds and end up with enough lather for 3 shaves. I don't know if you've used that soap yet, but it is outstanding. I'm happy to send you a sample of Ethos Colonia if you like.
Today's shave was excellent btw. The Lupo .72 continues to impress.
