Why each option
The xvidtune utility with the -show flag prints the current X server video timing parameters to stdout formatted as an XF86Config Modeline entry, making it the correct tool for this task.
xinfo-mode is not a real or standard X11 utility and does not exist in standard Linux or X.Org distributions.
xset-info is not a valid command - xset is a real X11 preferences utility but has no variant or subcommand called xset-info that displays Modeline-formatted video timing data.
xf86config is an interactive wizard for generating new XF86Config files from scratch and does not accept a -list flag to read or display current video mode settings in Modeline format.
xvidtune is an X11 client that queries the X server for current video mode timing values via the XFree86-VidModeExtension protocol. The -show flag causes it to print those values to stdout formatted as a Modeline line compatible with XF86Config, allowing the output to be copied directly into configuration files or used for display diagnostics.
