Saigai, it comes down to after doing your own DD, and what you end up believing. After all, YOU are risking your money.
I don't believe it is a matter of lying as it is more of a matter of individual interpretation.
Example you and I watch the same videos of the two doctors and come away with two totally different interpretations of what was actually said (Human nature).
In the end the ONLY thing that will make a difference is the performance of the company.
Best of luck, it is all a gamble.
