I'm gonna wait until the full remake story is out before deciding which is "better" but so far I really liked the remake, though it did stumble in a few areas i.e train graveyard and revisiting the sewers for the millionth time. I imagine the base story will mostly be the same but with more fleshing out of each area and truckloads of sidequests in every town, as opposed to OG where we just breeze on through after a single event per town. (SPOILER)Also it might try something similar to FF8 where we play through two separate timelines, the one with Cloud which continues the story as it were and the one where Zack survives and is the "main hero".

Gameplay-wise remake clears, mostly because it's actually somewhat challenging unlike OG, which was mostly braindead easy aside from the occasional difficulty spike boss battle. Materia system works just as well here as in OG, and I loved how each weapon actually now has a function and difference besides stats.

Also it's kinda funny because I think the remake improved every character EXCEPT Cloud, who just doesn't have nearly as much of a personality as he did in the original. In OG FF7 even just judging the Midgar portion of the game he had more agency, he showed more emotion, he got into conflicts with other characters, he cracked jokes (like when he joked about Aerith having what it takes to be in SOLDIER after escaping the church) etc. in remake he doesn't have much to say and just acts stoic and socially awkward most of the time.
