If your measure is a decentralization of power then nothing could be further from the truth. Davis consolidated power in Richmond in ways Lincoln never dreamed of.
I am not in the camp that faults either Davis or Lincoln for wartime usurpation of executive power. Lincoln was not the President of my ancestors, so criticizing the internal politics of a foreign country, the USA(1861-1865), is not my thing-hypocritical to do so.
President Davis's usurpation was done in desperation, so I do not fault him either as long as post war he knew a free republic would emerge in the south along the lines of the original founding intent (art. of Confederation). Nothing that Davis said post war leads me to conclude otherwise.
Lincoln usurpation of power was to destroy the republic of our founders. Conversely, Davis's usurpation was to restore the republic post war. Pretty much the same thing to different goals.
