Feather blades have no equal in my eyes. Sure, the blades cost a little more, but for good reason. Recently I haven't used anything but Feather blades in my Feather AS-D1. They are the sharpest and smoothest blades for my face.
They are both very good aftershave. Two of my favorites. Each is nice in its own way. The scents are similar but definitely different. While I enjoy the scent of AV, I like the scent of Floid Blue more.
I used this the other night. I loaded my brush with my normal amount of soap and it took forever to mix enough water in. I was surprised how much less I could use of the soap to make a sufficient lather.
