Coming from a place with proportional distribution, I can see there's value in a winnner-takes-all policy. For example, alternance is more likely (in Andalusia it took 37 years for a non-socialist government to have a chance at power). Also, representatives respond to their district's specific needs, which is good because you have one specific person to go talk to, and to boot off their seats if necessary (unlike a system where the politicians at the top of their parties ranked lists are pretty much guaranteed a position). There's no perfect system, and the grass is always greener, etc.
