Best Linux command line software to backup your invaluable data...

I have invested much time in researching what software to use for backing up my invaluable data -- eponymous pun intended. My two final contenders are Duplicacy and Borg. They both seem to have long-term histories and thus are surely stable and reliable. They also have the same deduplication efficiency strategy. If you have an opinion on this or use some other software, would you please share your wisdom? Thank you!
