I think some of the models mentioned here are not underrated just but their peaks are gone/slowing down,like Alana who once had ed in vogue Italia every other month and big campaign every season,she's decelerating in terms of her career and it is normal for models
Cato is so bland on the runway (imo) but always deliver strong printwork. Now all she does is Marie Claire, Elle and some vogue south america or taiwan.
