Better published figure on: Build volume.
What we like

Watch out for
- Single nozzle, so multi-color relies on AMS purging

No scored spec where it is strictly ahead; its case rests on the strengths below.
What we like
- Two nozzles cut filament-change waste
- 350 °C, heated chamber
- Laser upgrade path
Watch out for
- 31 kg and a big footprint
Verdict
H2S has a larger single-nozzle volume (340 × 320 × 340 mm). H2D adds a second nozzle. Same 350 °C, 65 °C chamber and 20,000 mm/s².
