I chose Hive 2 > Dune 3 primarily because I think the virtual oscillators sound better, and think both would be definite overlap. But, if that's OK, then Dune 3 is a great synth. If you have one you really don't NEED the other. Want is something else...
And I'm selling Pigments 3 on KVR because, no matter how many times I tried, I simply couldn't connect with it and had zero interest in continuing to try - a lot like the Peak when I tried it. Doesn't help that it's so CPU heavy - even Vital is lighter weight.
To be sure I'm on-topic: I think Hive 2 should've been on the original list, as well as Dune 3, Vital, and Pigments 3. All of them have the clean, modern vibe with lots of features, functions, and voices for atmospheric pads or cutting/pulsing basslines.
