I can't really say best, but my top 5 favorites for the console are . . .

1) (Amusingly) Valkyrie Profile - I love exploring in the game, the extremely unique (and fitting) way you learn about the people that join you, the visual style, the combat, the item creation, the skill system, the different dungeons according to difficulty, the small mysteries you encounter in the world, and piecing together Lenneth's story on the 'true' ending path. It is both my favorite RPG on the system, and my favorite game Tri-Ace has released so far.

2) Tales of Phantasia - ToP has a relatively basic story, but it still ends up being my favorite story in the series thus far, and this is one of the few RPGs I've played where I really like ALL of the characters that join me, not to mention Dhaos is one of my favorite villains in the genre. The PS1 remake did great things for the game, adding in a new playable character, heavily updating another, VASTLY improving combat, putting in skits, and improving the visuals.

3) Suikoden - While I can't deny the improvements Suikoden II brings to the table, the original is still my favorite in the series. I prefer the areas in the first game, I prefer the watercolored look of the character art, I like the antagonists more, I like the father / son conflict more, I like crumbling empire more; it's just a long list of small things that push it ahead for me.

4) SaGa Frontier - SaGa Frontier is a wonderfully open game, where your characters can be whatever you want them to be and you can go wherever (almost) you want to go, something that was a hallmark of the series for a while. Back from the original SaGa games, Frontier reintroduces monsters, robots, and mystics to franchise, each with different properties that make them unique and fun to use, and new to the franchise are combos, where you can chain certain techs together for big damage. Additionally, most of the main characters are provided a stronger narrative than was provided in the previous Romancing SaGa series, which helps provide the player direction in what could be an otherwise seemingly aimless romp. Unfortunately, the game is also a bit on the unfinished side, and it certainly feels that way from time to time, but it doesn't drag down the overall experience that much.

5) Lunar: Eternal Blue - People really like Silver Star Story. Like, REALLY LIKE it, but, I dunno, it never did as much for me as the sequel. Both are great, don't get me wrong, but, just like Suikoden I, it's a long list of little things that make me like EB more than SS. And the epilogue.
