My most efficient cartridge razors are schick xtreme 3 and st2. Can’t go wrong imo.
I was amazed by the schick. I normally use DE’s or Gem’s. When I am lazy or in a rush I reach for Trac II. I ran out of the Trac II carts and I had a package of these Schick 3 Xtreme Reloads, from a Christmas stuffer. Suffice it to say it did an amazing job it might bump the the Trac II for me. I will have to see how long the cart can last.
