I strongly disagree with above. "Cantarelli" mainline suits are entirely machine made. There is not a single hand-made stitch on Cantarelli mainline suits, so they cannot be compaired to Sartorio in anything other than perhaps siluette. Caveat is that Sartorio is soft tailored and fitting while Cantarellli mainline is heavily padded in shoulders and chest. Granted both are canvasses garments but I would rather compare Catraelli mainline to Brooks Brothers in quality and fit or any other machine made stiff suit made with canvas.
Cantarelli mainline is not in the same category as Caruso or Sartorio by a mile.
These generalizations are not true. I've handled Cantarelli's mainline items (and Cantarelli for BG) that are soft-structured, fully-canvassed, and have tons of handwork.
+1. Both are good, but it really depends on the line. Cantarelli higher end items have softer silhouettes - very Neopolitan - that is easily on par with Caruso. The items they make for other brands and their diffusion lines have very different characteristics: Cantarelli tailor (half-canvassed, shoulder padding, all machine-sewn), Cantarelli "Absolute Light Jacket" (extremely soft/unstructured). Caruso has more consistent quality, but I've even seen SP items entirely machine-sewn (although I've never come across a Caruso item that wasn't fully canvassed).
Cantarelli: quality in higher end line, soft tailoring; attractive cuts/structure in "Light Jacket" line (but not much if any handwork); lower lines questionable/completely inconsistent styling.
Caruso: fully-canvassed, consistent quality across lines, some structure; Sartoria Parma line typically has nice hand-detailing.
