I agree with most of what froote said.
While I very much enjoyed Dear Evan Hansen, my take was that it is The Ben Platt Show and I'm in the (minority) camp that expects this piece will be diminished when he leaves. Quite simply, I felt that the show itself (particularly the book) wasn't as good as Mr. Platt's absolutely phenomenal performance.
If it's a show you're sold on, I'd figure out a way to get in there before his contract ends in the fall. If you're on the fence, I'll just say that I thought Come From Away was a more successful production overall (a more cohesive combination of story, score, lyrics, and ensemble cast).
Your mileage may vary.
And now, scores of others will post to tell you why I'm wrong.
