While I'm traditionally leary about travel zooms, it seems the 18-105 f4 in particular has fairly good reviews. Phoblographer had really great things to say, as did Rockwell. Really the only knock is the 427g weight, which is fair considering the focal length range.
Regarding 6500 vs 6300 - the 6500 only gets 2.5 stops with its IBIS, which isn't that impressive honestly.
