Neither heater is a runaway winner because they’re effectively the same class of product with the same core specs: 1500W PTC ceramic heat, 70° oscillation, remote control, thermostat (41–95°F), and a 12-hour timer. Both also share the same main drawback in buyer feedback—some reports of units failing after around a year—so long-term reliability is the biggest trade-off regardless of which you choose.
If you want the most straightforward value pick on the provided data, the DREO Space Heater (Item 2) edges ahead due to its lower price and explicitly listed detachable filter/LED panel. The DREO Atom One (Item 1) remains a strong, quiet, fast-heating option if you prefer its personal/tabletop positioning and the same highly rated day-to-day experience.
