In a federal system there is centralized authority, while in a confederal system power is distributed equally among the states.
In a federal system power is distributed equally, while in a confederal system the states have less authority than the central government.

In a federal system, power is shared between a central government and regional or state governments. The central government has authority over certain issues, while the regional governments have their own powers and responsibilities. The distribution of power is usually outlined in a constitution or other legal document.

In contrast, a confederal system is a union of sovereign states or regional governments that have come together voluntarily to form a central government. In a confederation, the central government has only limited powers and relies on the states or regional governments for most decisions and authority.

Therefore, the main difference between federal and confederal systems is the degree of centralization of power. In a federal system, there is a centralized authority with a division of powers between the central government and regional governments. In a confederal system, power is distributed more equally among the states or regional governments, with limited authority for the central government.

The correct answer is:

In a federal system, there is centralized authority, while in a confederal system power is distributed equally among the states.
