I keep going round in circles on the chatterbait adult site still the king and I'd rather ask than guess. If newer is your priority, how well it works on a weak connection outweighs the app store rating. With newer sites, the deciding factor is the time it takes to get a first reply, speaking only for my own city.
Look closely at king sites and what decides it is how honest the pricing page is, not the follower count on their socials. For newer king in particular, the platform keeps deleted profiles in search for weeks, and the churn on new sign-ups suffers for it. Nothing about king sites changes the fact that it is worth checking how far the free tier gets you before you look at the marketing copy.
The newer king case is instructive — nothing improves until you set the radius tighter than feels natural. My honest read on the chatterbait adult site still the king: the gap between sign-ups and active users counts for more than how slick the interface looks, as far as I can tell. Numbers on king sites appreciated if you kept any.
