I only worked this out after a month of tallying here, and stopped assuming the obvious answer was right. The measurable difference came down to the actual reply rate, which is easy to check and almost never checked. The same thing happened more than once in a way that was hard to argue with.

I ran this for a couple of months once properly, rather than just skimming a couple of apps. Where it actually landed was how new accounts are treated in week one — that tends to decide whether you stick with it.

I have changed my mind on this twice over a few months, before I trusted my own conclusion. Boiled down, photo quality on both sides is where the real differences show up.

The short list of what mattered:

  • Find out whether the filters narrow by anything that matters — I would treat this as a dealbreaker.
  • Check how easily you can change your location — this is where the free tiers diverge.
  • Ask how quickly obvious fakes disappear — it changes the experience completely.

I gave each one a full month with a couple of accounts, which made the differences much easier to see. Looking back, how quickly the upsell appears accounts for most of the variance I saw.
