Myself, like many others, seem to build a "collection" from wanting to try out many different guns. After awhile, we realize what gets left in the safe when we go shooting.
I've tried Kimbers, M&P, Taurus, and so many others. Over the years, I've slowly started selling off the ones I just don't shoot much. Whether somebody loves the Glock, Sigs, or whatever...it sometimes takes us a few years to figure out what we want to focus on.
Doesn't mean that I don't go out and buy something new...sometimes at the LGS I hear something new and shiny calling my name...
