      Cup Diameter

      Both mouthpieces have virtually identical cup diameters at 25.40 mm / 1.0000 in.

      Cup Depth

      Both mouthpieces share a medium cup depth, so the sound character from depth alone will be very similar.

      Throat Diameter

      The Schilke 50 has a wider throat (6.75 mm / 0.2657 in vs 6.66 mm / 0.2622 in). A wider throat allows more air through, increasing volume and projection but reducing resistance.

      Which is better?

      Neither mouthpiece clearly dominates the other — the right choice depends on your embouchure, playing style, and the sound you're after. Try both if possible.
