QFE for field elevation, so the altimeter reads the height above the airfield and, ideally, ought to read zero at touchdown.
But what is this 'field elevation'? There's a 75 foot difference between the thresholds of our single runway and the tower's monitoring station is different from both thresholds. I've worked in places where the difference between the thresholds is as much as 180 feet. Then there's the question of how often the reading is updated,
GPWS/EGPWS calls out "Minimums" then the actual height during the final moments before touchdown anyway - "Fifty - Forty - Thirty - Twenty - Ten" - and can be pin-programmed to also call-out various other significant heights: there's around fifty different choices available to whoever sets the policy in your Flight Operations Department.
Not to mention "Bank Angle" and other choice criticisms of your approach technique...
