The latter probably requires a default resolution to be set in raspi-config (at least on the Pi4 - earlier models defaulted to VGA resolution).

If you are not planning to use VNC the first is preferable - you can always start GUI manually with startx when required if a monitor is attached.

My Pi boot headless with or without monitor.
