Despite Turnabout Intruder just being the last episode of the season it was in, it was still better than TATV.
That said, I'd put things in this order.
What You Leave Behind... great conclusion to the most epic story arc in Trek history, and actually had something of an epilogue for the series.
All Good Things... stunning single episode, definitely ended TNG on a high note.
Endgame... I don't even like it that much, but yeah... this is how comparatively weak the rest of the finales are.
And my thoughts on the other two are already on record.
