I used NoClone for the longest time and loved it. Czkawka has been my go to since NoClone hasn't been updated in a while and tends to crash.
The GUI is a bit awkward to get used to, like for instance I haven't figured out if you can browse a path, and filtering by path is a little different to me, but I'm still generally very happy to use it.
I used to use a program called NoClone, but it appears that somebody may have purchased it a while back and stopped development and made it kind of shady.
My old licensed version doesn't work very well, so I was looking for a replacement and as I have learned more and more about this program, I've been able to use it more and more effectively.
Edit: I should mention I'm a visual person, so I do use the GUI.
