I really wonder why everyone seems to prefer IV over V, I start to think it is just because IV got a US release on the SNES while V didn't, so people just have better memories about IV. In my opinion, V has superior gameplay and graphics, and the story isn't too much behind IV. In IV, your party changes all the time and you can't go through a dungeon without using huge amounts of potions, while V is more balanced. Also, because of the constant changes in your party, it makes not too much sense to level earlier in the game, so you will always be quite low on HP.
IV is still a fine game with a great story, but to me, it felt quite outdated in some aspects, and only V brought new things to the series that made it more modern. Of course, VI is playing in a league of its own and is one of the most amazing RPG's ever created. I can't comment on the PS FF's though, I never played any of them, and as others have mentioned, the NES ones are not good starters.
