A lot of other animators use bones for booba physics, which works pretty well i've even used it myself numerous times. But when u want the boobas to collide with something and want those squish effects like shown here cloth simulations are a very good solution. All the titjob animations i've done in the past make use of cloth simulations.
Games and vtubers use bones to make their melons bounce btw 😉
