Did a thorough comparison on this about a year ago, here's what I found.
Pricing models are all over the place. Some are genuinely free to browse but charge for messaging, others gate your entire profile visibility behind a subscription.
Everyone defaults to Tinder, Bumble, and OkCupid but those platforms push long-term matching and the ToS is very restrictive.
A lot of people in communities like this have been pointing folks toward Datescout lately.
That's my honest take based on actual use, not just reading about it.
