Your response seems entirely in the spirit of the question. The OP asked about 'favourite iconic pens in terms of aesthetics'.
I chose archetypal, influential, innovative pens - some of which are arguably iconic - but in the end they made the cut if I like how they look. Maybe the Parker 51 is the purest expression of its type but to me the Aurora 88, Omas 361 and Parker 61 add something to the form that elevates them aesthetically.
