I thought the FF7 storyline was more or less just like every anime plot I've seen duplicated a thousand times, and FFX's was much more refreshing. Also, between FFVII, FFVIII, and FFX, X's characters are the ones I like the most. Yuna is the first leading lady that I don't wish death upon. I don't like ANY FFVII characters, and the only FFVIII character I liked was Seifer (Squall had to go and ruin himself by getting with Rinoa).

So, y'know, everyone has different opinons. I like FFX more for its mystique and maturity (there weren't NEARLY as many stupid comments made) and its fleshed-out characters, but I can see why someone would like FF7 or FF8 more for the plots and battles (maybe I just haven't made it to the hard parts of FFVII yet, but FFX was much tougher for me, so far- I've been stuck at Sin's nose for months, as a matter of fact).
