The Poker 2 is self contained, no software needed programmable and mass produced. By now basically all the bugs have been worked out. Oha and all the mods.
The V60MTS has Matias switches and that's something that almost no 60% keyboards have, so that's worth more than basically everything the Ducky mini has going for it. You still get the same case compatibility you have with the V60 but sadly the keycaps will be harder to come by.
The Ducky Mini V2/2014 drops some of the compatibility, but gains the lighting, cursor keys, unique case and the side USB connection which I do think is a little better.
The V60 isn't 100% compatible with most of the cases at this point, it will work, but will still have some noticeable problems like dip switch clearance, slightly larger gap due to the V60 plate being slightly smaller than the pokers and not all the mounting screw holes match up. What the V60 has going for it is it's a little bit more simple than the Poker 2, has some good preset options and potentially cheaper.
Edit: Something else to think about is the [CTRL]ALT 60 $50 PCB with the controller pre installed, you provide everything else and build it how you want.
