I just did a first ride on this Union, and that was interesting. It is a true cross-over. It feels and rides like a town bike, with relaxed angles and upright riding position. But it does have the advantages of the drop bars with multiple hand positions, and one can ride in the drops without body parts getting in the way.
It's to an Alex Singer or René Herse what the Nissan Quashqai is to a Landrover Defender or Jeep Wrangler.
Which doesn't mean it's bad. Far from it. It's comfortable, it feels very solid, the Shimano deerhead stuff is excellent and the stem-mounted ratcheting thumbies are really nice.
I can see how this might have appealed to a certain audience. If you're new to drop bars and derailleurs this is a nice first bike to try them out on.
These are nice:
