Longer version: I finally got to the new Waveform, and this was the first thing I wanted to put into the test. I was expecting that Cubase's algorithm would be better (since 30 years of history, premium software, much more expensive, and so on, you know the stuff... ). But no. Although you can adjust few parameters in Cubase, the Waveform's 'hardwired' algorithm is simply better even without any additional tweaking.
Plus: If you don't pay an extra fee, Cubase can separate only voice and the rest. Unlike Waveform.
I just wanted to let you know...
