Optimal or suboptimal - Rahnev and Denison correctly argue that this ill-defined distinction is not useful when comparing models of perceptual decision-making. However, what they miss is how valuable the focus on optimality has been in deriving these models in the first place. Rather than prematurely abandon the optimality assumption, we should refine this successful normative hypothesis with additional constraints that capture specific limitations of (sensory) information processing in the brain.
