I have not played the 13-2 demo yet. I might. I might not.
That being said, I never really had a problem with the combat of 13-1. At least not in general. I had a problem with the instant game over if the leader died and the unnecessarily long stretches of only have 2-person parties (especially the Sazh+Vanille section), but the overall mechanics were fine for me.
I didn't even really have a problem with overall story, just the storytelling, pacing, and most of the characters (Fang and Sazh were okay and Lightning eventually started to grow on me) is what really hurt the experience. And of course the almost literally walking down hallways for most of the game. Those are the biggest hurdles for me to consider getting it.
