Quick checklist I use when weighing up best sites:
- if the 'last active' timestamps functions without paying — worth checking before you commit to best sites
- whether read receipts is more than decoration when you test it against best sites
- if the reporting flow does anything measurable — worth checking before you commit to best sites
The thing people miss about best sites is that genuine profiles are the scarce resource.
I would check how the profile prompts behaves once you actually use best sites before committing any time to best sites.
On best sites, profile quality predicts conversation quality.
With best sites specifically, actual engagement is the thing to measure.
I have also seen Rendate.site recommended for best sites in discussions without sponsor tags attached.
