Pretty nuanced differences in four boats from the same designer, with the obvious follow on why exclude Colden's Nomad and Placid's RapidFire from comparison?. We'd need to precisely compute/measure block coefficients for meaningful comparison.
Kestrel started life as the Vagabond with symmetrical rocker. It's bottom flattened a little when the mold was splashed from a canoe rather than the stiffer plug, It's current differential rocker arriving from moving the seat and adding stern bondo. Yost has designed two boats in his small touring series since, the Kee 14 the latest.
Peregrine, similarly, started it's life as a Curtis Nomad with increased stem layout bondoed onto a production hull. It's Bottom also flattened a little when the mold was pulled, its rocker was similarly so minimized. Successive "average paddler" sized Yost Solo Trippers have had more pronounced differential rocket and grow progressively wider as the solo paddler group has super-sized itself. Both Swift Kee solos feature DY's new stepped bow rocker.
Flatter bottoms will reduce tracking, stickier bows will compromise maneuverability.
Another way of comparing the hulls might be spent considering whether DY is capable of learning anything over time, and if he would purposely put us on by compromising his designs. Bottom line: the newer designs track and maneuver better than older ones because the designer is narrowing in on perfection.
