I had both Impossible burger at Burger King and Beyond Meat burger at Carl Jr. My very subjective opinion is Impossible meat is better.
IMHO I would not invest in BYND as they lose money and Tyson sold their stake in Beyond Meat is not a good sign.
OT: I don't understand the rash of IPOs of companies losing money like Uber, Lyft, Beyond Meat. The worst of all is the filing of WeWork, losing 1.9B on revenue of 1.8B. Biotech IPOs now look better
