I’m also on Windows, and using both Total Commander and Far. Often at the same time, but they’re both very good.
TC has better archives support, and better F3 previews for pictures and multimedia.
Far has slightly better FTP client, includes SCP client, has _much_ better F4 editor, and also has seamless command-line shell integration, i.e. Ctrl+O switches between blue panels and interactive shell, with synchronized current directory and commands to insert file names/paths into the shell prompt.
