I used XYPlorer for about 5-6 years until I made the switch to using Linux on all my machines last year. The scripting, speed, dual panes, customization, portability between machines (i used Syncthing to sync my configs between 3 machines) on XyPlorer are phenomenal and I've sadly not been able to find a Linux native file manager that's at the same level. Dolphin comes close but even with qdbus commands it sadly not as customizable as XYPlorer. I think it's the one thing I miss the most about Windows.
Because they lack something (for worse or better depending on one's requirements) equivalent to NTFS' MFT & USN Journal. Closest is building own file db by first-time full scan and then updating via fanotify/inotify. This is what FSearch tool does.
