The short-term at least, sounds worse.

From https://www.worldbank.org/en/country/chad/overview - "Chad ... is ranked last on the World Bank’s Human Capital Index.". This would indicate weak institutions which gives very little reason for optimism.

Déby was a ruthless dictator fighting against ruthless Libyan-backed Islamists (and to a lesser extent Boko Haram). Both are horrible. Déby murdered political opponents and oppressed his people. The rebels used child soldiers, executed PoWs, and just want to set up their own dictatorship but Muslim.

Currently, power has passed to his son, who is a general-major, so not much has changed, except he presumably has less power. This probably means more military influence in the country and less success against the rebels.

Best case, his son turns out to be a better dictator than his father or least have to concede to the people more.

Worst case, the discontent and political infighting leads to more instability and hardship for the country and the weakness leads to the rebels taking over.
