I have S1 Pro 3 but never use it because I don't like looking at it.
Tried Reaper, Samplitude X3 and Mixcraft. None of them made me want to change. The menus in Reaper are too are messy, Mixcraft just seemed like a kids toy version -of a DAW to me. I was hoping Samplitude 4 would bring an updated UI and then I might have been tempted, but that didn't happen.
Had a version of Cubase years ago and the customer service was dreadful, so I wouldn't go there again.
Bitwig/Ableton/FL have no appeal to me.
If Logic was available to PC users I think that might be tempting.
For the "industry standard" Pro Tools seems to be quite some way behind the curve at times and seeing as I'm never likely to be in the industry not having it is not a hindrance to me.
