I prefer GHW also but you can't go wrong with either. I think the gold really pops with the grey and it's so stunning! I think you can wear it both causal and dressy. Good luck in your decision!
I like the gold for this one, it's just the one i instinctively gravitate to but it's a personal choice, i think either as dressy or as casual, of course the gold stands out more
both are beautiful, but i say go for the gold! i think the warm hardware juxtaposes the cool gray color well. it makes the bag more versatile for a casual or dressy look. the rhw is beautiful, but it gives the bag an edgier vibe that is more limiting. just my opinion.
