They all sound very good to my ears, and I'm supposing one's preference would be subjective depending on how you like your acoustic piano sounds rendered. More importantly, and, which the videos do not convey, is the "finger to sound" response as you play...that is critical to most piano players; I know it's very important to me.

The only way to learn that aspect is to actually sit down at each instrument and play the pieces that are familiar to your ears.

Currently, I'm using a Yamaha P-95 for my controller, and it's midi'd to my Yamaha Tyros4. I like the Live!Grand Piano in the T4, especially after tweaking it for different genres such as Jazz, Classical, Pop or Country.

But, most importantly, I like the response of the rather inexpensive P-95 (and the older P-85 I used to use)...it feels like I'm actually "playing" an acoustic instrument.

Another extremely viable option is the new Casio PX5S which has a cracking good keybed (very responsive, and no aftertouch to interfere with the feel) and lovely tweakable acoustic pianos as well as it being a little monster of a synth...great price too!

Thanks for the links, AJ.
