Only Roland (Heavy) and Yamaha (Light) make their own arranger keybeds, the rest use OEM versions of Fatar keybeds and will all feel pretty much the same. (The more expensive the arranger, the more expensive the Fatar keybed that is used)
Personally I find them a nice balance between heavy and light.
Good luck with your further investigations, and make sure you have the latest update.
