Our Verdict
COWSAR Espresso Machine Wins

It offers superior functionality with its dual boiler, allowing for simultaneous espresso brewing and milk steaming, a significant advantage over De'Longhi's single thermoblock design. Furthermore, COWSAR features the optimal 9 bar pump pressure for espresso extraction compared to De'Longhi's 15 bar, and it is available at a more accessible price point of $407.57 versus $499.95. The De'Longhi La Specialista Arte Evo becomes the better pick for users prioritizing a compact design, quicker cold brew function, or who are willing to pay more for a recognized brand name and a specific cold brew feature, but it sacrifices dual boiler efficiency.
Bottom Line: COWSAR Espresso Machine is the better choice. It offers superior functionality with its dual boiler, allowing for simultaneous espresso brewing and milk steaming, a significant advantage over De'Longhi's single thermoblock design.
In-Depth Analysis
How they compare in practice
The COWSAR Espresso Machine stands out with its commercial-grade features, most notably the dual boiler system, a rarity at its $407.57 price point. In practical terms, this means home baristas can simultaneously pull a shot of espresso and steam milk to perfection, significantly reducing the total preparation time for lattes or cappuccinos. This capability contrasts sharply with the De'Longhi La Specialista Arte Evo, which employs a single thermoblock boiler. While the De'Longhi heats up quickly, users must wait for the machine to switch between brewing and steaming temperatures, making it less efficient for crafting multiple milk-based drinks in succession.
Another critical distinction lies in pump pressure. The COWSAR operates at an optimal 9 bars of pressure, widely considered the gold standard for achieving a balanced, flavorful espresso extraction with a rich crema. The De'Longhi, on the other hand, boasts a 15-bar pump. While a higher number might seem better, pressures exceeding 9-10 bars can often lead to over-extraction, resulting in bitter shots or thinner body if not carefully calibrated with grind size and dose. This makes the COWSAR's pressure a more forgiving and consistently ideal choice for quality espresso.
Furthermore, COWSAR includes a substantial 95oz water tank, drastically cutting down on refill frequency during busy mornings or when entertaining. The De'Longhi, while compact, offers unique features like an integrated cold brew function that prepares a single serve in under five minutes, a compelling draw for cold coffee aficionados. However, its manual frothing requires user skill, whereas COWSAR's dual boiler provides more reliable steam on demand.
In terms of value, the COWSAR presents a compelling proposition, delivering advanced dual boiler technology and ideal pump pressure at a lower cost than the De'Longhi. The De'Longhi appeals more to those who prioritize brand recognition, a compact form factor, or the specific convenience of its cold brew feature, even if it means compromising on simultaneous operation and optimal espresso pressure.
