On a scale of 1 to 100, I would put the LDS in the high 90s, and the Witnesses at about minus 10.
These days (well, around here at least) one encounters the Mormon missionaries all over the place. If they are not knocking at your door, they are approaching you out in the street. Of late, this has been happening all the bloody time!
By contrast, I cannot remember the last time the JWs came door-knocking around our district. It was certainly well before the pandemic. The most we see of them is when they occasionally set-up an apathy cart a literature stand at the local shopping centre.
Say what you will about the Church of the Latter Days Saints, but you would have to credit them for their zeal. (Something the JWs appear to have discarded many years ago)
