Joystick is loads of fun and essential if you are a realtime performance record (to DAW, or a recorder) type of workflow person.
I don’t even assign the X axis to pitch bend. Just other, more interesting modulation.
Remember that the joystick only modulates the current track you are in. But you can use that behavior to your advantage, as you can “lock” it into place by switching tracks.
You can also use it in the FX track.
You can also “play” FX parameters in the FX track on the keyboard by assigning FX parameters to velocity and aftertouch.
Multi-map is also a bonus, as it is more accessible on the AK.
If you have any pedals you want to use, route a patch out of the individual track output and mute it from the main, go through the pedal and then back into the external input which is in the FX track.
Here you can p-lock some FX sends.
If you have any issues with the smaller screen on the relatively big instrument, I use this Ikea laptop stand to tilt it up, as it fits underneath perfectly and the tilt isn’t too uncomfortable for playing the keys.
