I'm having the same dilemma - I'll be in NY on Monday night, July 8 and can't decide between 'Phantom', 'Chicago' and 'Tootsie'. I was going to go with POTO because it's been a while since I've seen it on B'way (about 17 years) but have seen it a few times on tour. 'Tootsie' did nothing for me from what I've seen from the Tonys, and 'Chicago' is just 'ehh' for me (I saw it about 15 years ago and on tour).
But I'm not completely ruling out Tootsie...
