My show was in Europe so maybe it's a whole different thing. The stage is pretty high, but not too far from the front row. I don't think you expect to be able to touch hands or stuff like that, of course.
It's so high you can only see half Jon, half Phil X and Hugh's head every once in a while. Forget about David, Tico or any of the screens except those at the sides of the stage and the "headlights" of the car.
Sound quality positively surprised me, though of course you can't expect perfection from there. I love hearing the delayed roar of the crowd.
All in all I would say it's worth it, but it really depends on your needs, priorities and the way you like to experience a concert (including pre-concert and post-concert time).
