Total Commander is just too great, never have seen anything coming close, maybe except Double Commander. Double Commander is the closest clone of TC, with many many features in place, but not as smooth and streamlined. Everything else i've tried on non-windows platforms is too barebones, including Marta.
Copy from older comment, regarding Total Commander:
powerful mass rename, advanced queue management for file operations, intelligent "resume" for larger file copying - it checks beginning/end bytes plus ~3 random points inside to to be sure you can continue on copying that huge file cut in the middle. You can color files/folders by conditions, e.g. files/folders created today are red and music files with bitrate 128 or lower are gray. Also, lister (built in preview on F3) - you can scroll through dozen-GB sized log file in seconds. Search is great, you can find duplicate images bigger than 512x512 and show them on file panel for any processing. And plugings. Lots of plugins. For archive formats, for lister, for mass-rename, for file system, for additional columns etc
I downloaded Marta and it looks and feels absolutely amazing.
But then I noticed that it is not open source, the sole developer has been on a break for at least a year, and the issue tracker mentions two bugs that may lead to data loss.
So I uninstalled it. I will look elsewhere for now.
