I've had more impossible burgers (from BK) than beyond, and I think I prefer the impossible taste a bit more, but only slightly. In a burger, with other toppings (tomatoes, mustard, onions, lettuce, etc)... the 'non-beef' taste is pretty minimal, in my experience, although I do notice a slight aftertaste. Haven't tried the new "beyond 3.0" which is dropping this week.
As a 'beef substitute' for every day cooking, haven't used it, but had other family members tell me they use the 'beyond sausage' (some spicy italian variation) in their everyday cooking to replace previous sausage use and they love it. They've gone totally vegetarian, have tried multiple meat substitutes over the years and think beyond is generally the best.
Have been trying ways to reduce meat consumption - going for blackbean substitutes in some situations, beyond/impossible burgers when available, etc. Not sure I'll ever go totally 'no-meat' but I do notice I have far less red meat consumption compared to 6-7 years ago.
I agree with another poster that the high sodium is a problem, and is possibly keeping some people away.
