Speaking from personal experience, I've been eating a lot more plant-based meals now that Beyond and Impossible Beef are available in grocery stores. I wouldn't say I'm completely vegetarian but I'm 60% there.
Impossible Foods is only 8 years old, and look how far they've already come.
Additionally, Burger King definitely doesn't make the best Impossible Burger (and not every Impossible Whopper tastes the same--like regular burgers, there's slight variation in quality depending on who is at the grill). I had it at a local restaurant, and it was one of the best burgers I've ever had.
