Yes, it is better! Part of the goal is to provide a "gateway patty" to make it easier for meat-eaters to reduce their consumption. Good for their health, good for the environment, good for the animals.
(Also, I've been vegan for years and _love_ the Impossible burger.)
Also the impossible burger has about the same amount of calories as an 80% lean ground beef burger, so it's no better as far as calories are concerned.
