Best piano vst

I am still considering my options. The Bitsonic freebie for example sounds awfully good albeit not 100% authentic. The more I think about this project I am not sure authentic is the most crucial consideration. I am not playing classical music and solo piano is not happening so it becomes a question of what works best sonically and where the recording budget would be best spent. I do appreciate the suggestions and I will eventually pickup something really good if I don't do it now.
