I like FFXII too, it's one of the best for me :P
I just don't understand people who complain about the gambits, I never used them the first time I cleared the game... I remember there was still a "!" mark when I was around 87 hours in the game and checked what it was and then I said "aah, it's this thing that was shown in a tutorial near the beginning of the game, let's try to use this"... and a few minutes later, I was like "crap, my characters don't do what I want them to... bleh, this thing is useless" and went back to selecting everything manually.
Anyways, I think this is one of the FF games that I've played the most, it has a lot of content and secret stuff and a pretty big open world... I like that in FF games.
I don't know where I would rank it though... Final Fantasy VI is number 1 and Final Fantasy VIII is number 2 for me... I don't know if I'd put this one on third place out of the ones I've played.
By the way, Final Fantasy XII looks pretty good on the PS2 emulator, It's worth replaying it on PC if you really like it. It looks waaay better than it does on the PS2.
