I see where you're going with this and I think you are correct.
The first RPG I saw was FFIX, a family friend had it, I was 9 years old at the time and the only thing I remembered was the battle music and the "monkey-man".
The first RPG I played was FFV, RPGe ROM, when I was 11 I got my first laptop for typing notes as I had problems with writing as a child (Still sort of do, I get bruises and sore joints when holding a pen because I'm a pansy).
A member of staff said "hey, do you want 300 games?" and I was like, sure why not. So he plugged in his 128MB USB drive and pasted on ZSNES with a butt-load of ROMs.
It had FFII, FFIII and FFV, I knew about FFIX so I wanted to play the "latest" FF game on the SNES...And started FFV! I played FFIII that summer and was confused as to why the graphics were 10x better than FFV but in my childish mind I thought "Well, FFV has more customisation and is a lot less buggy so maybe they simplified the graphics so they could make a better game".
So my favourite RPG is FFV and second favourite is FFIX.
EDIT: To try and justify this; I have played IV to IX in the series, I like them all for different reasons and dislike them for different reasons, but IX to me is the best example of an accessible and easy to pick up game, fun to master, and it will sit on my shelf of good game design, V to me is incredibly well balanced and structured, so is also up on that shelf, whereas VI has too many characters that stand in cutscenes looking awkward and it's very easy to neglect a character in VI, VII is very simple but the playable story has no depth, it's all very much single-track story, FFVIII has a story that was rushed, a shitty first disc and gameplay that advertises to be overly complex, but is secretly quite good, IV is just as simple as VII with a story that's has a tiny bit of depth in it.
