Cup Diameter
The Giardinelli Helleberg has a cup diameter of 33.30 mm compared to 31.25 mm on the Denis Wick 3 — a difference of +2.05 mm. A wider cup generally produces a fuller, darker tone but requires more air support.
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 3 has a wider throat (8.78 mm vs 8.35 mm). 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.
