This looks nice! I like TUI programs for this purpose. Previously, I've used Beyond Compare 4 by Scooter Software (GUI, free to try), it's nice to have more options because diff -r doesn't get you very far. I also like the ability to find duplicate images or any files regardless of location with Czkawka (Github qarmin/czkawka).
