I did a quick check since FF8 is the best Final Fantasy, and of course the remaster is shit:

1. The original had a 15fps cap in battle, but the menus ran at 60fps. So the Renzokuken indicator always scrolled buttery smooth. The remaster has 16(?!) fps cap in battle, so you get constant jitter since 16 doesn't divide evenly into any TV refresh rate. But worse, the menus update at 16fps now. So Renzokuken is fuck hard to nail now since it's a high latency mess.

2. NO ANALOG CONTROL. WTF IS THIS 1997?! FFS the original had analog control!!

3. The backgrounds are not upscaled at all. You get nice sharp clean models over a shitty low res background, which ruins the aesthetic. Like, seriously. There are so many really high quality upscalers there days, and the machine learning ones look fucking great. Filter that shit.

Skip it. Just replay the PS1 original. The 'remaster' is shit, so don't waste your time or money. If you remaster a game, you owe it to at least be as good as the original. This is worse.
