I've been using System Rescue for longer than I can remember. For the most part, I use gparted to manage the partitions on my computers (I dual-boot Windows with GNU/Linux - currently Garuda-KDE-Lite), but on a few occasions I have used testdisk to recover partitions following some fatal error (usually caused by my lack of attention when clicking/pressing the Enter key, IIRC). I keep a shortcut/desktop link to the System Rescue Documentation on both my Windows and GNU/Linux desktops so I can find out how to use some new-to-me tool/utility when things go awry. System Rescue has been a life saver for me on many occasions,
