I have a feeling it'll have the intellectual quality of the Instagram comment section, which is worse than the Facebook comment section, which is 10x worse than Twitter.
But I agree if there is heavy integration with the rest of Meta's products I'll be less happy.
Surely this is about who or what you are following though.
Personally there is very little crossover between what I follow on instagram and twitter. So the quality of the discussions vary greatly.
On Twitter I follow developers and product people. The quality is better on Twitter, but it's definitely declined because of engagement seeking over the last few years.
