FFV is a great game. The battle system (Job/Ability system similar to FFIII and FFT) is one of the best in the series, if not the best, and it was the most addictive system for me. Maybe because of that, FFV has the record of my longest time playing on a row, 17 hours (from 12 PM to 5 AM). While the storyline may seem quite weak, I noticed that it makes a lot of sense and has a lot of depth on it when I played through the game for the second time. The character development could have been better, but the characters are still likable, and I liked the side characters too.

The music is a bit different from some other FF games, but it's very beautiful and enjoyable, IMHO. Nobuo Uematsu was being quite creative on this game. For example, the opening theme ("A presentation") works just perfectly with the opening sequence. The game is relatively short, you can finish it in 20-30 hours, but it's still a fun game. There's also three different worlds to explore, which is quite cool.

The PSX version has annoying load times, sound quality is weaker than in SNES and the name translations are weird (X-Death, Salsa etc). So far I prefer the fan translated SNES version, but I'll wait and see how FFV GBA will turn out until I make up my decision about my favorite version.
