If I remember correctly, that ending is quite short and doesn't really have much going on, but (SPOILER)there's quite a bittersweet part in the end when Marle flies off with the balloons, and she ends up at the top of the Death Peak. She sees a shadow of Crono in the horizon, and she runs towards him as the screen fades to black. I'd suggest saving that ending for New Game Plus since all those side quests before the final battle just aren't the same without Crono, IMHO.
