      Cup Diameter

      Both mouthpieces have virtually identical cup diameters at 27.00 mm / 1.0630 in.

      Cup Depth

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

      Throat Diameter

      The Denis Wick 2AL has a wider throat (7.24 mm / 0.2850 in vs 7.01 mm / 0.2760 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.
