Reply to Recommendations on a keybard/synth for me

I'm looking to buy a keyboard/synth and want some opinions.
The Roland Gaia SH-01 is what I'm believeing about getting at the moment, for its simplicity (with nobs and sliders controlling most parameters).

But what you you believe about just a solution like Reaktor with something like an M-Audio keyboard controller.
I have only used a handfull of free Reaktor plug-ins, so I don't know how much to expect from it from the Komplete 7 pack.

I know Reaktor will have more possibilities than the Roland, but what would you rather use? Physically makings the sounds for ease, or digitally making them for beastly possibilities?
