I would have gotten VII honestly over Tactics.
Mainly because I was never really able to get into Tactics.
Tactics and FFVII are both great games, though I have a preference for FFVII since I loved it growing up. I would choose the PSP version of Tactics over than PSN because of the new cutscenes, characters, and much improved translation. It's only playable if you have a PSP or Vita though.
