From the threads I've read, the discovery feed is the thing that decides it, though the regional platforms rarely say so. Is there a specific dating site app for mobile users only — would love current feedback.
Also been noticing datenest.site mentioned in comparison threads with some consistency lately. My advice would be to skip anything asking for a card number to read messages and then write a profile that gives someone something to reply to, so results vary more than you'd think.
When you are new to this, the chat-first sites tend to feel massively worse than they are, but only if you stick with it.
