The most noticeable differences are:
1. Crown Guards on the ARF are a tad fat and therefore will need to be reshaped
2. Crown on ARF is slightly smaller so a gen crown would be a good replacement. Since the ARF crown is smaller it accentuates the fat crown guards
3. The lugs on the ARF are marginally fatter therefore does not look as proportionate as the gen. It looks blocky
4. Datewheel magnification is incorrect.
5. Crystal is not as nice therefore a gen crystal will be a great replacement.
Overall the dial and insert look pretty good.
