No, not strong! You don't wanna flip that coin between a possible one-hit wonder-like winter (2015-16, 1982-83) or no no snow at all (1972-73, 1997-98)...Moderate is best!
And really...perhaps when it's weaker, you still can get more moderate events...that's something, at least...most weak-moderate Niños seem to hit average snowfall...
