Graces= X-2 (people love the gameplay but can't stand the story)
Here's what I can think of:
FFIV - Tales of Rebirth
FFV - ???
FFVI - Tales of Destiny
FFVII - Tales of Symphonia - Aged badly but most popular and considered a classic
DoCFFVII - Tales of Symphonia DotW - Crap game
FFVIII -???
FFIX - Tales of the Abyss - A beloved gem too, but kinda obscured for some reason.
FFX - Tales of Vesperia - Great gem all around, some issues but still great.
FFX-2 - Tales of Graces - Best gameplay but crap story
FFXII - Tales of Xillia - Some people hate it, some people like it. Rushed in the end.
FFXIII - Tales of Zestiria - Incredibly polarizing, It looked like the next coming of FF but it fell flat.
