I currently use Tabac, which I might say is the best there is, but I am curious about Proraso. How does it measure up on the Tabac scale and does it give you freeze face?
Definitely YMMV. I do like a good Tabac shave. Although the scent is kind of heavy and warm for summer; it makes an excellent autumn/winter soap. If I had a tallow based spring/summer equivalent, then I'd probably retire the Tabac to using it only autumn/winter. I use Bigelow which is, of course, Proraso re-branded and find that it is an excellent spring/summer cream! Or if winter just isn't keeping your body cold enough then it makes a fine addition in January as well. The first time I used Bigelow my face was on ice cubes! Now? My face still feels chilled but it's more like a menthol chill that Aqua Velva or Skin Bracer gives you. That said following up a Bigelow shave with a cold splash does give you instant cold.
Performance speaking? YMMV.
Scent producing? YMMV.
Latherability? YMMV.
Cold factor and nice for spring & summer? Proraso/Bigelow
Warm factor and nice for autumn & winter? Tabac.
