My basic requirements were: snapping to vertices during add/split Easy to move around/zoom in/out/pan while editing reliable Fortunately, I was able to assess the process across most GIS packages, and this how they fared: MapInfo - Editing is quite laborious, involving several steps for simple tasks.
