OpenStreetMap
To an editor user for osm edits , I would definitely find nothing more comfortable that it. However, with my recent exposure to josm and all its abilities, life has been greatly simplified. It is embedded with a number of tools, more to it very simplified shortcuts to making viable edits, more to it is the minimal internet consumption hence a multi million edits can be performed in a blink of an eye. The ability of it being installed without cracks makes it much ore suitable. Thanks to josm because editing is now becoming an addiction.

The usual teach process is to start with the simplest easiest to understand tool and, as the student progresses to introduce them to a more complex tool .. finally to introduce them to the most complex tool
Having been subjected to this process over many years I now chose the most complex tool to learn first .. saves a lot of learning things that I later have no use for.
