Comparison of the major workstations / stage pianos:
When buying such keyboards it’s always best to lay your hands on them, spend some time with them, and checkout the various sounds and features by yourself. It would be a good idea to take a good pair of headphones along.
In case you are looking for specific features that probably only one of these offer, then I guess it becomes much easier to select.
