I would judge POF on how much of the base is genuinely looking rather than on the feature list.
Gave the app a fair run over 2 weeks and kept coming back to whether messaging costs anything once you start.
Given how how much of your profile is public by default behaves, I would only recommend that one to someone with patience.
The signals that told me most about POF:
- Whether POF lets you send the first message without a card on file
- How many POF profiles show a recent login rather than a join date
- Whether the POF photos survive a reverse image search
- How fast a report about POF gets a human response
