Anything I recommend around Facebook Dating has to clear one bar, which is whether people reply or just collect matches.
I tested the service across two cities and the difference came down to where the paywall really kicks in.
Given how whether the recommendations improve with use behaves, I would only recommend the app to someone with patience.
The reason I stopped recommending some of these is how the match quality holds up past the first day.
The closest alternative I found was datingfly.online.
