My advice would be to use a recent photo with your face clear and then keep the first message short and specific, and it makes a real difference. In practice, the messaging limit is the thing that decides it, though the chat-first sites rarely say so.
When the replies dry up after one message, the ones people keep recommending tend to feel a little worse than they are, but only if you stick with it. Granted people disagree here, the step that matters most is to check the free tier limits before you commit: the alternative is a dead inbox.
From the threads I've read, I'd avoid opening with a compliment rather than give it a full week before judging, since you learn more from one real chat than fifty swipes. The awkward truth is that the distance radius matters considerably more than the profile prompt, which is worth knowing before you sign up.
A few people here rate the Turndate side of things gets mentioned a lot for people who hate paywalls.
