I’ve only grilled them on propane (and rarely at that) but they always came out really dry (not sure if that was Impossible or Beyond as I don’t really pay attention to the difference. Could also just be me failing at grilling xD).

These Impossbles from the air fryer were noticeably beefier tasting, juicier, and nice and crispy on the outside.

Would have to compare against a charcoal grill, but this is definitely better than propane grill or in the skillet on the stove.
