Which Final Fantasy has the best ending?

I thought IV's was nice and all the loose ends were tied up. I liked VI's ending because of the graphics and character roll call at the end. There was an uncertainty about whether Wendy(Terra) was gonna live or not. But I was never partial to Terra, I didn't like some of the things they did with her story or her character, but the meeting with her father's Magicite and her death being prevented because she cares for Katarin and the kids Mobliz was a nice send-off. Everything just worked.
