I would find it helpful to know what your amplification situation is. Are you going through a FOH PA, or using your own? Are you running stereo or mono?
I would recommend Pianoteq. Last I remember, you get to choose 3 piano models with your purchase. So you can download the demo and play around with the sounds to see what works best for your situation. Within each model, there's dozens of presets that will usually get you in the ballpark. If you get the Standard or Pro version (I have the former) you also get the ability to micro-adjust things that can affect "bite", like reverb, hammer hardness, string length, mic placement, EQ, etc.
But again, download the demo and see for yourself (the demo comes with all the piano models so you can try them all out).
