I can only comment on the existing production, of course. This is a sparse, yet high-tech and brilliantly told piece of theater about an autistic boy who is mathematically talented. The show is funny, entertaining, challenging, and a bit disturbing. The entire cast is beautifully committed to telling the story, and the technical aspects of the production are very creative, visually striking, and at the level you only get at this level of professional theater.
I saw the main lead in the cast. It's a physically challenging role and he was up to it, and again, very committed to the role (no walking through it here). I had read that while this actor is excellent in the role, the original lead on Broadway may have made you feel a bit more of the hurting underneath, so portraying a hair more emotional depth to the character. I could see that there's a bit that more could be mined there. But this actor was still strong.
One tip for selecting seats. This is a show that, in spite of the occasional "wow" visuals, is intimate and would be best seen as close as you can get. Getting balcony seats will water down the emotional effect of the play. The closer you are, the more immersed you will be.
