I don't agree about TNG being closest to TOS.
In fact GR's attitude about Star Trek is pretty different between the two series.
His outlook was refined IMO not really changed all that much the main difference was that he didn't have network on him, which is why he broke his contract and left his position as Producer, he nearly turned down TNG for that matter it was only because of nature of syndication that brought him back, it allowed him the freedom to do what he wanted to do.
