My rule for dating app and chat combos work now is simple: check how the chat behaves on a weak connection on day one.
Took me about 5 weeks on the app to work out that the real question was how precise the filters really are.
If you are only browsing, the chat is fine. The moment whether the algorithm is doing anything useful matters, it changes.
Most comparisons of the room skip whether the algorithm is doing anything useful, which is the part that matters.
Your mileage on dating app and chat combos work will vary by city more than by anything else.
