From Wiki-
The Plan called for the general government to be administered by a President General appointed and supported by the Crown, and a Grand Council to be chosen by the representatives of the colonial assemblies. Many objections and difficulties were debated, addressed, and resolved whereupon the plan was unanimously adopted by the delegates of the Albany Congress. Copies were then sent to the Colonial Assemblies and the British
Board of Trade in London.
[2] The Plan was promptly rejected by both sides. "The colonial assemblies and most of the people were narrowly provincial in outlook, mutually jealous, and suspicious of any central taxing authority."
[3] Many in the British government, already wary of some of the strong-willed colonial assemblies, disliked the idea of consolidating additional power into their hands. Instead, they preferred that the colonists' focus remain on the forthcoming military campaign. The Board of Trade never sought official approval for the Plan from the Crown. Instead, they proposed that colonial governors, along with some members of their respective councils, order the raising of troops and building of forts, using money from Treasury of Great Britain which would later be repaid by an Act of Parliament laying a tax on America.
It seems to be a bit more centralized and seems to have taxing authority which the Articles did not.
