Watts, or airflow
Is a published airflow figure worth paying more for?
Both have the thing that matters most on a dryer — separate heat and speed controls — and both include a diffuser. The AC9140B adds an AC motor, an airflow figure, a third attachment and a salon-length cable.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
Take the D3198 for almost any household. It has the separate controls, the cold shot, the removable filter and both attachments — everything that decides whether a dryer is usable.
Take the AC9140B for long or thick hair dried often. An AC motor and 150 km/h are the two specifications that shorten the job, the 7 mm (0.28 in) nozzle does precision work no other dryer here offers, and three meters of cable changes where you can stand.
Because moving air is what dries hair, and wattage only describes how much electricity the motor draws. A more efficient motor can move more air at lower stated power. Airflow is published on one of these two, which is one more than on most dryers anywhere.
The motor type used in salon dryers, as against the DC motors in most household ones — heavier, and generally longer-lived. Remington names it on the AC9140B and does not on the D3198.
2200 W · 3 heat + 2 speed, separate · cold shot · diffuser and nozzle
2200 watts, three heat settings and two fan speeds on separate controls, a cold shot, a ceramic-ionic grille, and both a styling nozzle and a diffuser in the box.
Best for: Everyday drying where the diffuser matters and the budget does not stretch.
2400 W AC motor · 150 km/h · 3 attachments · 3 m (10 ft) salon cable
A 2400 watt AC motor with a published airflow figure of 150 km/h, three attachments including a 7 mm (0.28 in) precision nozzle, a true cold shot, a removable filter and a three-meter salon-length cable.
Best for: Drying thick or long hair often, where airflow and cable length stop being details.
