  We analyze two different fermionic systems that defy Mott localization
showing a metallic ground state at integer filling and very large Coulomb
repulsion. The first is a multiorbital Hubbard model with a Hund's coupling,
where this physics has been widely studied and the new metallic state is called
a Hund's metal, and the second is a SU($3$) Hubbard model with a patterned
single-particle potential designed to retain important features of the
multiorbital Hubbard model in a set-up which can be implemented with SU($N$)
ultracold atoms. With simple analytical arguments, and by means of the exact
numerical diagonalization of the Hamiltonians for a minimal three-site system,
we identify a common scenario where the interaction-resistant metal emerges as
a compromise between different terms, each leading to a different insulating
state.
