I prefer that version over the Pixel Remaster because they added some backstory and personality to the characters. Not much, but enough so they're not just some anonymous warriors anymore. The intro is different from the original. 3D graphics are nice too (but PR has a better soundtrack).

The job system is not as good as FF5's but is interesting enough. You have to choose a certain job at some point of the game. The main issue is when progressing in the game, you won't always find new equipment (especially armors) for your current job, and if you want to go on with your party, you end up wearing outdated stuff and getting your ass kicked real hard. Having to change jobs just to wear newer and stronger equipment prevents you from having the party you really wanted. For that point too I prefer FF5, where you can get armors for any job at any time.

garbage, bought it, removed it from account.
because it has issues with settings/launching.

will do the same for the IV remake and rather buy the pixel remaster.
