Really no noticeable difference however when you hut the right directional button it fast forwards in increments where you hit it 3 times and it goes a minute, 4 times it goes like 3 minutes all approximate, I didn't memorize the exact values, still getting used to it but it's not a constant 30 seconds per click like it was.
All in all everything works just fine with either version but I figure I'd go with the latest and greatest lol.
