One rather important consideration I left out ↑↑↑ is camber gain. With a strut suspension, the lower you go without getting into correcting the geometry, the slower your camber goes negative to compensate for roll as the suspension is compressed still further (consider what the outside suspensions are doing while cornering). With struts up front and either a multi-link IRS or just about any stick axle suspension arrangement, this becomes an understeer effect.
