Reply to Looking to add to my setup- Akai MPD Series or Midifighter 3D/Pro?

I've been DJing for a little over a year now and I've been dabbling in production. Currently, I'm using an Akai APC20 and an MPK Mini to run Traktor and Ableton (not at the same time).
Mind you, this addition is meant for both, but leaning more toward the production side of things. I'm fond of the pads in the MPK Mini, but I also notice that there is a lot of love for the arcade buttons on midifighters.
The contenders at present are the Midifighter 3D, the Midifighter Pro, and the MPD 26 or 32.

I'd like to get an opinion on which is better suited toward production. Velocity sensitivity is not an issue.
