Which is faster, the AtomStack Ace Pro V2 or the Ortur Laser Master 3?

On paper the AtomStack is faster: 400 mm/s is about 24,000mm/min against the Ortur's 20,000mm/min. Real cut and engrave times depend more on power settings and material than on top speed.

Which has the larger work area?

The Ortur, at 400 x 400mm against 400 x 365mm on the AtomStack. The difference is 35mm on one axis, enough for some larger blanks.

Do I need an air pump for either one?

The Ortur 20W ships with a free Ortur Air Pump 1.0 and a built-in air tube. The AtomStack does not include one, so budget for an air assist if you cut wood or acrylic often.

Which is safer to leave running unattended?

The AtomStack lists flame detection, a tip-over alarm and resume engraving. The Ortur lists none of these. Neither should be run fully unattended; stay nearby either way.

Is the Ortur worth extra money over the $369 AtomStack?

Only if its price comes in close to $369. You gain speed headroom, a bigger bed and a bundled air pump, but you give up the AtomStack's flame and tip-over safety features.

Which handles fine detail better?

The Ortur's square 0.08 x 0.08mm spot and 256 gray levels favor smooth shading and fills. The AtomStack's 0.02mm stated accuracy and rectangular spot favor precise line work.
