I always liked the Excelsior class. (Judging by the replies, I might be the only one!)

I’d think that time travel episodes should be considered based on what time the crew is coming from, instead of where they go. So Voyage Home is still between STIII and STV, and First Contact is between Generations and Insurrection.

This will lead to minor troubles, mainly with Enterprise, since it has a few references to First Contact and The Tholian Web.

Also there’s that one far future episode of Voyager where a copy of the Doctor has to clear Voyager’s name, which doesnt involve time travel and must therefore be watched between seasons 2 and 3 of Discovery.
