My experience is a little different, I find that drawings (CAD anyway) produced by architects are worse than ones produced by draftsperson, let me explain before I get linched!
Architects are aiming for the design of the building not the drawing of the design, they are often under pressure handling multiple projects and performing multiple aspects (letters to contractors, schedules, planning etc etc etc) as a result layer management, technical accuracy etc. can take a back-seat. Its easier when under pressure to edit a dimensions text than to move the wall(s) to which the dimension is pointing. Why use layers when changing a lines colour has the same VISUAL effect?
A 'good' draftsperson's creation is the drawing(s), producing drawing is 'their' skill. They usually get a good clear run at a scheme without the other distractions mentioned above and can therefore concentrate on layer management, neatness, presentation, and most importantly accuracy.
I started my career as a draftsman but please don't take the above as a biased comment, its just my experience of working with and for both. I could never have drawn anything had it not been designed first.
On more than one occasion (a lot more than one actually) I and others have 'defied' an engineers/architects instruction to ensure its RIGHT not just 'looks' right. And on just as many occasions have been balled out by the said engineer/architect only later to be proved right (invariably on-site).
The only good thing about being linched by a bunch of architects is that it will take then 3 years to finalize the design for the gallows
