I came at this after wasting time on the wrong options in my own time, and a few things became obvious quickly. Every time I compared them, moderation quality is easy to check and almost never checked. That difference held up every time once the first fortnight was out of the way.

I made a spreadsheet, embarrassingly while comparing them, so the sample is at least reasonable. The recurring theme was the actual reply rate — it explains most of the complaints here. The same thing happened in a way I could measure regardless of how I framed the profile. Others may have found the opposite in the end, depending on where you are.

What is worth five minutes of checking:

  • How much the app relies on push notifications — worth asking about before you invest time.
  • How the app handles people who never reply — surprisingly hard to find out in advance.
  • How easily you can change your location — worth two minutes before you commit.
  • Worth confirming whether read receipts exist — it matters more after the first month.

I resisted the urge to switch too early with a bit of patience, and stopped assuming the obvious answer was right. The short answer is that the size of the local pool is the thing people consistently underestimate.
