Ah the QFE/QNH debate - almost as old as aviation itself!
My observation is that those who have been brought up on one system cannot see the merits in the opposing system until they have actually operated same.
But what is really important is that altimeters and their settings are managed correctly with a clear understanding about what the instrument is telling you etc.
To highlight to US-trained PPLs the lunacy of UK altimeter setting procs, I take them from Brize via the Faringdon VRP to White Waltham, then back via the Oxford/Kidlington overhead to the Burford VRP. This requires Brize QFE, then the Cotswold RPS (another utter anachronism), then Benson QFE, then London QNH, then White Waltham QFE, then London QNH, then Benson QFE, then Cotswold RPS, then Oxford/Kidlington QNH, then Cotswold RPS, then Brize QFE. That's 5 different altimeter settings on the way to White Waltham and 7 different settings coming back - madness!
Is this not a case for having one simplified altimeter setting, ie Aerodrome QNH?
