The LDS missionaries actually go out of there way to speak to people. More than a few times, I have had them approach me while walking along the street.
The dubs, by contrast, will typically walk right past you, while heading for the front door of the house that you have just left, and where there is now nobody at home. Talk about being more interested in going where the people aren't!
Whatever their faults, the Mormons at least attempt to give a more effective witness to the community.
Their religion, too, is very much family oriented - whereas that of the JWs is in no way family friendly.
If I had to make a choice, it would be the LDS (although still one hell of a choice to have to make!)
