Athens was more democratic because it is government by the people instead of government by those elected by the people.Greek democracy created at Athens was direct, rather than representative: any adult male citizen over the age of 20 could take part, and it was a duty to do so. The officials of the democracy were in part elected by the Assembly and in large part chosen by lottery in a process called sortition.
