Aluminum Door Quality

What goes into a well engineered aluminum door? All three of these are used on luxury homes but can you guess cheapest to most expensive from looking at the simplicity or complexity of the engineering and design?

The one in the middle is a modified commercial door (screw cover missing in this image). It has almost no weatherstripping compared to the two more residential doors.

The door on the left is thermally broken with superior weather seal design and not seen in the photo are three dimensionally adjustable super smooth hinges.

Think of doors like automobile engineering. Cheap car doors feel like it but you can FEEL the precision engineering in a luxury car door operation.
