I could see and hear everything very clearly from U, other than a tiny bit of the top of the stage, on which nothing happens.
I wouldn't necessarily feel the need to be that far back, but I opted for those seats because they were in the center and on the discount code. I'd say for this show it's better to be in the center than terribly close.
And as far as the show itself goes, I really enjoyed it. Haven't seen Sister Act (I have tickets for a few weeks from now), but based on the response on here, it's great as well. I'd say if you're a fan of the creators and the material, go for it. But, at this point, probably just pick whichever show appeals to you most.
I understand the part about being limited by the number of shows you can see per year (I'm from Ohio as well!), but you have already made good choices. Loved Book of Mormon and Priscilla, and it would probably be a real toss-up if I had to choose between Catch Me and Sister Act.
