I have to disagree with you to a certain extent.
First of all, the sharpness of the 1.8@1.8 is sharper than the 1.4 (be it D or G)@1.4.
As you stop down to F/2.8, the 1.8 is still sharper than both the 1.4 in the center, but on the corners the 1.4 does better.
Again as you stop down to F/4, the 1.8 is sharper than the 1.4 in the center, but loses out at the corners.
The reason for one not being able to get a sharp picture with a 50mm F/1.8 is the user problem and not the lens issue.
I've had friends who had taken stunningly sharp images with 50mm F/1.8s at 1.8 wide open, even i sometimes do that myself when i really need F/1.8.
Just remember, the DOF at F/1.8 is really shallow, a lot of times you don't get it sharp because of the shallow DOF and not really because the lens ain't sharp.
explanation frm the experienced user
