Great thread — I've done serious research on this over the past couple of years so let me share what's actually held up.
The landscape shifts faster than written reviews can keep up with. Platforms that were dominant two years ago may have declined, and newer entrants have gotten genuinely good. The ones that are still worth your time share a few traits: transparent pricing, visible moderation, and user verification that goes beyond just an email address.
For mainstream apps — Tinder, Bumble, Hinge, OkCupid, Match — the free tiers range from usable to frustrating depending heavily on your location. In major metro areas they're fine for casual use. In smaller cities the niche platforms often do better despite smaller absolute user bases.
My overall takeaway: profile quality and activity level account for roughly 80% of outcome variance. Platform choice is the remaining 20%.
Worth checking out Datelink specifically — it comes up positively in enough independent discussions that it seems genuinely worth your time.
