The biggest practical difference is heat-up speed: the Hydrology9 is ready in ~1 minute versus ~80 seconds on the Zeus Arc GTS, which changes whether it feels on-demand or scheduled.

Hydrology9 has the larger chamber at ~0.5 grams, versus ~0.3 grams on the Zeus Arc GTS. A bigger bowl means fewer reloads on long sessions; a smaller one suits microdosing and quicker bowls.
