I think this is rather impossible to answer.

One of the biggest issues is that context changes over time.

FF7 in particular is nearly unplayable by modern standards, imo. The amount of transition times (random battles with 20 second intros and 20 second outros) and lack of QoL features make it ridiculously hard to swallow. There's also an expectation of mindless "grinding" that has largely written out of modern games. Even the remake uses side missions, which at least have some interesting elements to them, rather than pure mechanical "go spend 2 hours killing basic enemies".

OoT has many good things going for it, but the live controls and weird camera behavior have been largely solved by games nowadays.

If you consider them in the context of the current time, both were unlike almost anything that had been seen. And given the price/console exclusivity at the time, I'd venture that very few people actually played them at the same time in their contexts.

Both were absolute revolutions of their time, which isn't capturable anymore. It reminds me of the movie Predator. It became the foundation for so many things, but modern movies have taken everything that Predator did and did them better. By modern standards it's a clichéd action movie with basically no plot. Makes it hard to judge.
