I've had the exact opposite reaction to the change. So many common actions seem needlessly difficult. Take –for example– joining a wifi network. In Unity, you'd click on the wifi icon in the upper-right, then click on the network you want to join. Two clicks. In Gnome, you click in the upper-right, then click on the wifi icon to expand options, then click on "Select Network", then click on the network you want to join, then click "Connect". Five clicks! It's absurd.
The story is similar for things like power settings or selecting sound input/output sources. I wish the Gnome team would imitate macOS or Windows instead of coming up with their own uniquely frustrating interfaces.
It's been a long time since I've used a full desktop environment, but back sometime around Ubuntu 10.04 it was by default the two-click Unity version you described. Even nowadays (on 16.04) if I start nm-applet, it's just two clicks.
