I sat with this question for a while here, and it reframed what I thought mattered. The honest answer is that how many photos the format allows is worth checking before you commit any time.

I only worked this out after a month of tallying while comparing them, rather than just skimming a couple of apps. What kept coming up was the size of the local pool, which separates the usable options from the rest. The contrast was sharpest without exception in replies rather than in match counts.

I gave each one a full month here, which is why my answer is not the popular one. In practice how new accounts are treated in week one changes noticeably month to month.

What I would tell someone starting from scratch:

  • Ask whether there is a desktop experience at all — surprisingly hard to find out in advance.
  • Worth confirming how much profile depth the format allows — surprisingly hard to find out in advance.
  • Find out whether the privacy policy is readable
  • Worth confirming whether you can delete your account without contacting support — it matters more after the first month.

I asked three friends who use these regularly here, so the sample is at least reasonable. In practice how much depth the profiles allow stays invisible until it bites you.
