I have used a Kaweco Sport and have owned dozens of Hero pens. If you are talking about the 200, I believe you are referring to the 14k gold nib pen. Though I have not personally used that pen, I don't see why it would be a troublesome writer.
You hear people comment on the lack of quality of Chinese pens, but that generally refers to their sub-$10 pen that they produce for the local market. The 200 (as well as the 100 series) seems to be their "luxury" gift lineup.
Nonetheless, I would not take the unnecessary chance and just go with the Sport. You can get interchangeable nib units, as well as a variety of different finishes from a transparent demonstrator, to classical black/blue/maroon, aluminum(AL Sport), coloured plastic (Ice Sport), and even carbon fiber options.
Don't let the 14k nib fool you into thinking that the Hero will write nicer!
