I rushed SISTER ACT on Saturday and found the view to be just fine. The stage doesn't seem as high as it has been in the past (for SHREK/COLOR PURPLE). I don't believe they're selling the side sections of the front row as rush - just the center section.
The view was great; the only thing you miss is essentially the performers' feet if they're toward the back of the stage, and some minor neck-craning now and again easily makes the seats worthwhile. The energy of the show is pretty infectious, so I had a great time being up close to this one. I don't know if I would have wanted to see it further back...
On Saturday, I got there at 9 (box office opened at 10) and was eighth in line. There seemed to be 16 tickets; I was the second to last person to get tickets (the person behind me got a single since someone ahead of us bought a single).
