I don't like Bernie's positions and I would never vote for him, and based on positions alone if I had to choose between them I think Warren would be mildly more palatable from a policy standpoint, it's clear Bernie is the credible party here.
Warren has a history of lying about identity politics issues to benefit herself. She lied about being an Indian (feather, not dot) for professional advancement, she lied about being "fired for being pregnant" and she never misses an opportunity to portray herself as a victim of men, white people, etc. Bernie can be caustic and obnoxious, and he is incredibly hypocritical at times, but I am not aware of Bernie outright lying.
ἡ δὲ κἀκ τριῶν τρυπημάτων ἐργαζομένη ἐνεκάλει τῇ φύσει, δυσφορουμένη, ὅτι δὴ μὴ καὶ τοὺς τιτθοὺς αὐτῇ εὐρύτερον ἢ νῦν εἰσι τρυπώη, ὅπως καὶ ἄλλην ἐνταῦθα μίξιν ἐπιτεχνᾶσθαι δυνατὴ εἴη. – Procopius
