I guess to be more helpful, there are class I-III very close by. For much more I had to drive a few hours.
I've sat in both at a local store.
For the Ethos I am a big fan of the seat, and fit. I worry about the agility.
For the Fusion, I like the appeal of it being more agile, but worry about the tracking.
For both, I am curious which has the best flat performance.
