I don't have anything in FDE. Purely as a matter of personal taste, I don't care for the color, but if other people like it, no problem. I see people wear shirts and ties and sport coats that I wouldn't wear, but if they like it, it is none of my business what they wear.
The only practical consideration is that I prefer black on a carry pistol, not only over FDE, but over stainless or anything else, because I carry IWB strong side with a cover garment. My unproven hunch is that when my sport coat flaps open for a fraction of a second, the pistol is black in dark shadows, and gives an observer less of a reason to think about what they saw. In other words, if someone sees something shiny in that little dark hole that opened momentarily, it might catch their eye and make them wonder what it is, more than seeing just a bit of darker black in the shade.
Maybe this is off base - I haven't tested it in any serious way - and it certainly doesn't apply to pistols that aren't carried. Heck, one of my favorite pistols is a Beretta 92FS in Inox. It breaks my rule, but it isn't a carry pistol. Buy what you like.
