If you're talking Italian soft soaps, then RazoRock's new Linea Artigiana soaps and Vitos Extra Super All'Olio di Cocco stomp all over Cella, and P.160 for that matter. They are slicker, and provide better cushion than both Cella and P.160. The Vitos smells closer to Cella. These two "soaps" will kill SSAD quickly.
On the flip side, if we're discussing hard soaps, then as previously mentioned, you have MWF, AoS (or Valobra Sapone per Barba), and D.R. Harris.
