So far Musgo Real is my favorite for both scent and performance.

And the last few shaves I've discovered that it makes an effective pre-shave as well. I rub small amounts into my beard with water until I get a milky consistency and then let it sit while I work up the lather in the bowl. This moisturizes my face in a way that plain water didn't. So my skin doesn't pull the moisture out of the lather and the lather lasts longer without drying. I'm getting a better shave.
