How does Aerossoft Robin DR400 X compare to Katana 20-100 4X ?

The Katana 20-100 4X I already have and the Robin DR 400 X seem interesting. But I also have a slight impression that it's similary to the Katana or am I mistaken ? Would like to here from people who have both. My hope and expectation is that the DR 400 X is

1) More fps friendly

2) Easier to handfly

3) Better and more realistic flight model

I find the Katana to be very sensitive. For example even a slight input on rudder and the coordination ball goes wild around. The VSI can swing up and down very much.

Will I be more content with the Robin DR 400 X ?
