Do you have altimeter bug's? If not, then it is far better to go to QFE when necessary.
Airlines use QNH as a means of keeping terrain clearance simpler, but it does require a bit more mental gymnastics if you try and fly a 1000' agl circuit, as is the norm in GA.
It can just create confusion which can be minimised by sticking to QFE approaches as the rest of the industry uses.
Sticking to standard practices can help cut down confusion.
