@Starbit: White Gold is not exactly "Yellow gold plated with Rhodium"

White gold is actually made by mixing yellow gold with metal alloys that give it its white appearance (usually nickel, copper, zinc and silver).  This white metal is then covered with Rhodium (a member of the Platinum family) in order to give it a more shiny luster and protect the gold.  (FYI: Even yellow gold that is not pure 24K is also mixed with metal alloys to give it strength as pure gold is actually way too soft for practicality). 

And you are right, silver is a fairly soft metal which bends, scratches and dents fairly easily.  Further it tarnishes naturally over time.  Sometimes  if an item has a lot of intricate detailing it can be difficult to buff off all the tarnish in all the small creases.  While gold does also require a  bit of maintenance (cleaning, replating with rhodium and buffing) but I take mine back to my jeweler about once a year to get this done (for free) and it's a much finer metal especially to set gemstones in (this is why you usually will not see FINE gemstones and especially diamonds set in silver).

My fiance is getting a titanium band. It has a "gun metal" silver look to it, but he really likes it (he thinks it looks more "manly") Titanium is a strong metal so you won't have the same problems you would with silver, and its also very inexpensive.
