One major advantage of the unitary system is that it tends of make government

The unitary system tends to make government strong and stable. This is because power is concentrated in a central government, which can make and enforce decisions quickly and efficiently. The central government has the authority to implement policies throughout the entire country, without having to negotiate or compromise with regional governments. This can lead to a more consistent application of policies and laws across the entire country, which can promote stability and predictability. Additionally, the central government is typically better equipped to respond to national emergencies or crises, as it has more resources and authority than regional governments.
