Best Final Fantasy

[Balipu]

Okay, let's see what the first night brought us. Well at least it was a night for me.
So, a few interesting facts for fans and devs:
Currently VIII is considered to have the best story, followed by VI and the VII compillation. IX Is the fourth and out of the main series the XIII trilogy is ranked the lowest
The best combat award is held by VI, followed by VII and IV. Apparently people really hated the combat of the original XIV as it is the 23rd out of 26.
Progression and customization: VI, VII and VIII. Surprisingly, the MMOs are farely low with XIV and XI being 7th and 11th respectively.
Soundtrack: You might be surprised to learn (I think both One Winged Angel and The Extreme beat Dancing Mad but even I was surprised) that VI is only the 4th. The top 3 are VIII, VII and IX(Uematsu's personal favorite)
Protagonists: Currently Terra is in the lead with Cecil and Zidane tied at second place and Cloud and Squall tied at third. People like to make fun of Tidus, but he only barely lost to Bartz and managed to rank ahead of Lightning and the Onion Knight. Oh, a message to the Kingdom Hearts tema: People like Roxas more than Sora.
The top 3 coolest villains are Kefka, Sephiroth and Garland. Incidentally the highest ranking XIV villain is Nael van Darnus who is far ahead Gaius and Lahabrea.
In villain fight Nael is even farther ahead, with the top 3 being Kefka, who is only barely ahead of Ultimecia and Sephiroth at third.
The most popular lady is Terra followed by Aerith and Rydia. Yuffie, who was decisively leading before the reset is now the 10th. Prishe is ranked ahead any woman from XIV. Speaking of which for quite some time now Yugiri is ranked the highest, closely followed by Yda. Most surprisignly Minfilia, queen of uselessness is ranked ahead of Y'shtola.
45.45% placed Cid Highwind at the top. so unsurprisingly, he leads with an overwhelming majority. He is followed by the original Cid from FFII and Cida Haze from FF III
And now for Gilgamesh: GREEEEEEEEEG! Yes, ladies and gentleman, the XIV version is the most popular, followed by his original appearance in V and finall VIII.

This is the current situation but it is far from conclusive. I will report again when we get several more answers.

hmm, probably ff13 (the first one, i pretend the other two dont exist) for me. i enjoyed the combat system and the inter-character relationships quite a bit, except for vanille.

ff6 as a runner up, though it's protagonists IMO arent quite as memorable, going for the quantity-over-quality approach.

I know, right. We have a blond girl who used to serve the empire and was saved by Locke from certain doom because she looks like his ex-girlfriend. Then we have a blond girl who used to serve the empire and was saved by Locke from certain doom because she looks like his ex-girlfriend. Locke himself is suffering from survivor's guilt as he couldn't save his ex-girlfriend. Then we have Setzer who is suffering from survivor's guilt as he couldn't save his ex-girlfriend. Shadow puts a spin on this as he couldn't save his best friend and Cyan has survivor's guilt cause he couldn't save his entire kingdom. We have 3 token non-human character members Umaru, Mog and Gau(borderline example) and all 3 of them fight with limited player input.
In constrast the 14 player characters of Type-0 are very different. Of course most of them don't get much character development and we only get a shallow glimpse into their character, but even the two smart kids (Trey and Queen) differ in significant ways.

I haven't played a lot of the games, actually. I loved FFX and X-2, as well as XIV ARR though.

FFXIV ARR, is definitely my most favorite favorite though.
