Impossible burgers are awesome and I've had quite a few. It also really depends on how it's made and how it's dressed up - as with any burger. My only lingering issue is that it is a highly processed food, and psychologically it helps to know what you're eating.

As is a huge portion of the food consumed by people today, including things that are marketed as forms of meat. The difference here is that the climate impact of mass-production of beef and the associated mass scale animal cruelty is mitigated.
"If you think all this talk of laboratory food is ridiculous or unappealing you really need to spend some time discovering where your current food supply comes from. Most of the nitrogen molecules in your body right now were created in a factory using the Haber Bosch method. Natural gas is used to fix atmospheric nitrogen into a usable form needed by plants. Enormous amounts of this synthetic fertilizer is what makes it possible to feed seven billion people. Take away that factory made nitrogen and our crop yields would drop like a stone. Without Haber Bosch nitrogen half the humans on the planet would starve to death. Synthetic food grown in fermentation vats is just a matter of cutting out the inefficient middle steps of agriculture. Like it or not it’s coming to fish sticks, chicken nuggets, and meatballs near you. And you might not even notice."
Yeah, it's basically an ethical burger, which, if that's what you're looking for, that's great. While I can tell it tastes different, when dressed up in a burger it hits the spot just like a hamburger does. The problem is when people try and convince themselves that just because it's vegetarian it's healthy, which isn't the case at all. After all, Oreo's are vegan.
