Color--pros & cons
You could try to be objective: the white is non-metalic so it will be easy to repair. But all whites are different and not "pure colors" like the old non-metalic blacks, so there is still a color-match problem. The silver will show light dirt and dust a LOT less than the white (or the black or other dark colors). I lined up the silver, bluewater, and titanium up in a row, and the bluewater was clearly the best and richest of the bunch. (Oops, that was not as objective as the first comments. Guess which color I have.) So... my suggestion is to get a print-out of all the cars equipped as you like that are in the region, pick one and, if necessary, offer an extra $300 or so to cover the swap with another dealer. You'll be much happier in the long run.
