You probably prefer it just because you haven't used it enough. As you said, you've only used it a few days, ever.
One Commander has been the best application I've found for file management on Windows (even though it's not perfect - to me).
However, I also use Linux and the built-in file manager (for many) is Dolphin and it has a big problem that makes me unable to use it.
I searched around for some other options and found several other 'Commander' type options. Tried some and found one that's usable,
but they all have pretty ugly interfaces and other weird things going on. I miss One Commander because it's the closest I've come to
finding something that's perfect for me. Obviously, with the tools you've used, there's no option to port it easily to Linux, but for
those of us who do use it... We wouldn't say no to a Qt (or something) based one (even if you left out a lot of the more advanced features
that I don't use anyways)
