Verdict
Fourier GR2 leads on 3 of the 4 weighted dimensions both makers disclose.
Fourier GR2 leads on payload (15 kg vs 10 kg), max speed (1.5 m/s vs 1.2 m/s) and battery life (3 h vs 2 h).
HUBO-2 Plus leads on degrees of freedom (41 vs 40).
Left out because at least one manufacturer does not publish a figure: price.
