I have both pro (Home desktop) and enterprise (Work laptop). I don't notice a difference. But we don't really take advantage of the group policy very much.
It used to be Home versions couldn't get more "Enterprise" features, like full partition encryption and the ability to join a Domain. Naturally GPO doesn't apply to a home user.
These days, I run Pro on pretty much everything and don't seem to miss anything. Perhaps "Enterprise" comes with less Candy Crush and other bloatware pre-installed?
