I rode with cages (I think real cyclists call them "clips," by the way) for 19 years. They do have their advantages in that they can help you really dig in without slipping off the pedals. But they were always a nuisance at stop lights and they made chopped meat out of my sneakers in no time. I just never realized there was another option.

For me, pinned platforms are perfect. They lend tons of support to the "jump on and ride" attitude I have developed over the past few years and they are, overall, a pleasure to ride with. To answer your question, one of my first rides with them was a 60-miler I took last year that was at least half in a torrential downpour. Not once did my soaking wet, cheap new Balance sneakers slip off the pedals or even come close to it. Nor does this ever happen on my commutes.
