Waking up: light or sound
Winner: Hatch RestoreThe Hatch is a sunrise alarm. Hatch describes its light moving from red to orange to white before your chosen alarm sound, so the room brightens before anything plays. Its product page gives no brightness figure.
The Loftie Clock is not, and Loftie says so plainly: its nightlight can be set to come on with your alarm, but it is not a sunrise simulation, and Loftie sells the separate Loftie Lamp for light-based waking. The Loftie's waking is done by sound, through its two-phase alarm. If you sleep in a dark room and want light to start the job, the Hatch is the one of these two that does it.
