Air flossers vs. water flossers: which cleans teeth better?

I read on https://lifehealthhq.com/airfloss-vs-waterpik/ (mirror):

In a study published in 2012 in the Journal of Clinical Dentistry, clinicians found that that the WaterPik water flosser reduced significantly more plaque from tooth surfaces than the AirFloss.

The study was conducted over a four week period, comparing two groups who used either a Sonicare AirFloss or a WaterPik, in addition to regular brushing. The study found that:

• The water flosser was 80% more effective for gingivitis reduction than air floss.
• The water flosser was 70% more effective for plaque reduction.
• The water flosser was 2X as effective for plaque removal from lingual surfaces and 3X as effective at the gingival margin than air floss.

The amount of plaque reduction was compared in several areas:

The studies we have at the moment indicate that the WaterPik is the better option, but that’s just the short answer.

The study was published six years ago (in 2012): are air flossers still less efficient than water flossers?
