Ranked in these QuestionsQuestion Ranking
Pro Great and complete search
On other options it can be difficult to find the addons or dependencies . You will always find them in Synaptic.
Pro Full featured and easy to use
Pro Most functional package manager out there
Over the years Synaptic has survived while others try to be as good. The trend is towards simpler tools, but whenever you need functionality, synaptic usually trumps other options.
Con Slightly difficult old fashioned interface
While it is true that Synaptic is feature packed, it just so happens that a lot of the features are not inclusive of each other and using it often feels like herding cats. You'll note the endless number of categories, universe vs multiverse, custom filters and so on. It's great if you're into that sort of thing, but awful if you're just looking for a package.
It takes something that should be simple, and turns it into a complete mess.
