This is the right question. The answer is mostly what the app leaks to other members.
I would judge it on whether you can hold a conversation without paying rather than on the feature list.
Gave engage in free sex talk a fair run over 5 weeks and kept coming back to whether the safety tooling is more than a checkbox.
Assuming you are not paying, whether the algorithm is doing anything useful is where that one gets tight.
Where engage in free sex talk stands or falls is how quickly it starts asking for money.
Someone in another thread pointed me at how Datebound handles it and it was a fair shout.
