So, what are the differences?

FE's remind me of 1911 pattern pistols. The holy grail for many because of their desirability, beauty and nostalgic rep. Some shoot well from the factory with factory ammo, but to make one run like a champ with modern high performance rounds, they often need to be tweaked and customized by a knowledgeable gunsmith ($$).
Why would anyone spend so much time and money on a 1911 or a 427 side oiler when there are loads of Glocks and 385 series engines that can do every bit as much or more?
I guess if one needs to ask, they really just don't get it and probably never will.
