Which company makes the best coffee percolators?

According to Real Simple, as of 2015 the best coffee percolators are made by Dualit and Cuisinart. Both models chosen by Real Simple are electric percolators that plug into a wall socket rather than heating on the stove top.

Percolators make coffee by boiling water inside the pot, circulating it through coffee grounds contained in a separate basket. Because the water passes through the coffee basket multiple times during this process, percolators can be used to make more robust brews than drip coffee makers. Because brewing time can be set by the user, percolators allow more control over the strength of each pot of coffee.
