Only played through 7 and 8. So 7 would be my favorite so far.

Final Fantasy VI is my favorite game from the series (Characters,musci and gameplay are fantastic)
I have no expectations for Final Fantasy XVI

This is like asking a Mom to choose her favorite child

I don't think a main line final fantasy game will top FF XII for me, cos neither Matsuno nor Eito are working on the series anymore, It's followed closely by FF VIII (I couldn't find it so I had no problem voting for XII) and then FF IX

7, 9, 10, and 12 are godly. I'd say 12 with 7 a close second.

I will go with X in the poll, but VIII is definitely up there too.

VII by a pretty wide margin.
IX and X are also really great though.

Bonus: I don't really have high expectations for it, but I'd love to be proven wrong.

My favourites are VI, VII and XII.

I expect that the fanbase will treat XVI unfairly and tear it to pieces, also that so-called experts will cry a lot about how this is not Final Fantasy anymore yada yada wah wah.

FF9 is my favorite. I really wished they kept the coop feature in the remaster.

Final Fantasy IX. It was the first Final Fantasy game I ever played.
