Which Should I Play

Hi all, just wanted to know if there's any hardcore RPG fans out there and if so then my question is which of the Final Fantasy's is better between Final Fantasy IV (Japanese version for SNES) and Final Fantasy IV (US version for GBA) because I know that Final Fantasy II (US version for SNES) was a watered down version of the original Final Fantasy IV (Japanese version for SNES) so is the US GBA version of Final Fantasy IV just like the Japanese version Final Fantasy IV for SNES with better graphics and add-ons or is it like the watered down Final Fantasy II for SNES with better graphics and add-ons? Thanx for your time.

Does anyone know??

I've heard that Final Fantasy III (US version) is the best of the SNES Final Fantasys. I think that's VI in Japan if I'm not mistaken.

Well, I've played the FF IV (GBA, US) for a while and i liked it, but I never played FF IV (Japan) on SNES
