JOSM

Summary
JOSM offers a large set of features and useful tools for a wide range of editing styles: It will either read in GPX tracks from your hard disk, or download them from OSM. Aerial imagery can easily be downloaded as a background for tracing. JOSM also supports photo mapping and audio mapping. Once you have completed your edits, you can upload them to OSM.
Pros
  • Fast fluid panning and zooming. Near-infinite zooming for super-precise mapping.
  • Can work offline using downloaded data files, and can work with local photo and GPX files
  • Advanced editing functionality e.g. make nodes of a roundabout into a circle.
  • Bing and other aerial imagery immediately available as backgrounds for tracing.
  • Highly configurable and extendible via plugins.
Cons
  • The finer points of the interface take a while to learn.
  • It requires Java 6 to work (not a big problem for most people)

Potlatch 2

Summary
Flash online editor.
Pros
  • It's right there on the 'Edit' tab
  • It allows quick easy immediate editing. Map changes can be sent back to the server as you make them.
  • Bing and other imagery immediately available as backgrounds for tracing.
  • GPS traces available as a separate layer
Cons
  • It's not intended for power users (who are already excellently served by JOSM) or those who want the speed of a desktop client.
  • Zooming and panning prompts a map fetch (not as fluid)
  • photo mapping and other file accessing features are not possible
  • Requires Flash (not a big problem for most people)
  • It is not possible to work fully offline

Potlatch 1

Summary
Old version of the Potlatch editor offering quite a different editing experience, but it has similar pros and cons as the current Potlatch 2.
It is still available on the edit tab (hover over the tab with your mouse).
