In my head there is no conflict about this either, and I readily agree with this thinking. It is just that Sans Serif goes hand in hand with Helvetica after all, and I don't think it is exaggerated to say that everyone throughout the world would agree. Of course it is a great typeface, but I believe that one should not be fixated on the association of Sans Serif = Helvetica. For me, when I hear for example 'Sans Serif', then immediately Helvetica comes to my mind, even though I don't think that it is the best Sans Serif out there. Even if they were in the way of the reading process, I still think they form splendid letters. Inside my head, there are a number of forms of Sans Serif typefaces, and I cannot put aside any single one of them.
