I have Juno DS-88 and a VR-09. The Juno has far better pianos, the VR-09 has better organ. As far as the synth sounds go they're not easily comparable. The vr09 is (weirdly) how I imagine an old juno with it's 3 osc engine, the Juno DS is how I imagine an M1 with it's rich complex pads and effects. There's a good chunk of overlap of course, they're similar in lots of ways. I haven't messed with the Axial stuff because it's on loan from my dear old Dad.
