Since the cloud client is the "mother" of them all, I post it here.
This is just a little comparison of how the UI, specifically the menu bars, of the Adobe tools are different at a point where you actually don't see the need for them to be different. Sure, there are many Adobe apps and those like Acrobat are total outsiders, but comparing Photoshop, Indesign and Illustrator reveals quite a lot.
"What do you want to tell us?" you might ask now and I actually cannot say. My basic thought is that I wonder how and why the UI are not just the same.
Menu bars:

What do we see here?
- The home button isn't always next to the icon
- The AI logo icon looks weird
- The ID icon is smaller than the others
- The home symbol of PS is smaller
- The top bar of ID is bigger in height than the others
- The menus are vertically centered in the top bar with PS and ID, but not with AI
Next, menu:



What do we see here?
- The bezel around the menu items isn't vertically centered with AI, perhaps that goes with the other topic above
- The bezel of ID is higher than with the others
Next, the right side:
Upper is AI, then comes PS, then ID
What do we see here?
- Smaller close button with AI
- No Adobe Stock search field in PS, though it would make more sense there than in ID
- No "Search help" field for PS and ID
- Different approach to switch work spaces -> in AI it's a button, in ID it's a dropdown with name, while PS has none
The weirdest is how PS reacts to menu switching. See video. It has this irregular interruptions where it blanks the menu items.
