Both are mid-range all-in-one machines with a built-in grinder. The La Specialista leans on a dual boiler for simultaneous brewing and steaming. The Barista Pro leans on ThermoJet speed and a larger portafilter.

This page covers the original La Specialista (Arte), since that's what's usually meant by the name without a suffix. DeLonghi also sells Arte Evo, Opera, Prestigio, and Maestro versions with different grinders, tamping features, and grind settings, so specs can shift meaningfully if you're looking at one of those instead.
Yes, its dual Thermoblock system is built specifically to heat water for brewing and steam for milk texturing at the same time. The Barista Pro's single ThermoJet system handles one at a time, though the transition between the two is close to instant.
The Barista Pro offers 30 grind settings, a figure that shows up consistently across sources. Grind step counts on La Specialista models vary by version, and we didn't find a reliably confirmed number specific to the base Arte model, so we're not stating one here.
The Barista Pro uses a 54mm portafilter, while the La Specialista Arte uses 51mm. Both ship with pressurized and non-pressurized baskets.
