Don't mean to add fuel to the fire, but I would see Lopatkina. She's a living legend and some day you will spend many-many cold winter nights telling your grand-children about that time you saw her live.
Vishneva can be seen on a regular basis dancing with ABT during their NY season, and Obraztsova is quite young, while every chance to see Lopatkina on our shores can easily turn out to be the last one.
My second choice would be Kondaurova, but that's just my personal opinion
In any case, with luxurious casting like what we are being offered by Mariinsky this summer, you simply cannot lose - all these ballerinas are absolutely great.
