Midi controller question please help!

I want to add a midi controller to my pc and vci setup
I am looking for something that will do multiple cue points for cue point juggling, select/control effects in traktor pro, and play prerecorded samples and loops (and be able to switch back and forth between loops, cues, and effects throughout a set).
There are a few controllers I have been eyeing…
1. Ean’s alternative to the lemur

2. akai mpd24
3. or combination of the korg nano control and nano pad
I am wondering what the best midi/combination of midi controllers is for my mixing?
If anyone has advice or experience with these controllers please let me know I want to employ them into my future sets.
Thanks!!
