VI is the best in the series by a long shot. The villain is the best, the characters are all memorable and well fleshed out, the story is superb (I didn't cry at VII, but there was one scene in VI that made me cry a bit), the mechanics are all well executed, the music is fantastic, and it is one of the best-looking SNES games. And even as a WRPG fan, I still love VI
Also, it's one of the few JRPGs that Yahtzee likes, so if you agree with what he says (and even if you don't), you'd be doing a disservice to yourself not checking it out. Also, it is coming out on PSN, but it isn't out at the moment. I'm pretty sure you can get it on the Wii though, or if all else fails, just download the SNES ROM
