I think All Good Things...
was just about perfect. By far my favorite.
was not as bad as some people think, IMHO. I do think it was too abrupt, and did not deliver on Voyager's homecoming.

These are the Voyages
, well I think it might have made an interesting stand alone episode, but as a series finale it was poorly conceived.
doesn't count, IMHO.
