The only negative side of Total Commander is I'm extremly used to it - been using it since mid 90s. When I compare alternatives on Mac I'm searching for exact keyboard commands, navigation patterns, etc. I'm using Crax Commander, but it's not the same.

TC is probably one of the reasons I don't care that much about problems in newer versions of Windows, I don't use Explorer, I don't use windows search, text is viewed with Lister and not Notepad...

I don't know about Total Commander because that appears to be Windows-only, but twin-pane "Commanders" (named after NC) do seem more popular in certain circles. They're still in wide use in Eastern Europe. Commanders have also influenced Dolphin, which has a built in twin-pane view (but it's not a commander because it lacks the typical keybinds) and there's a commander called Krusader that is a better fit.

Also a big plug for Far:
