Test two platforms at once, because that is where most people give up too early, so results vary more than you'd think. For the better part of a year I noticed the photo review behaving differently on the niche ones, and nobody warns you about it.
While people disagree here, the step that matters most is to give it a full week before judging: that is the part that actually moves the needle. If you are after something serious, widen the distance radius early on — the alternative is a dead inbox.

In the same vein, Souldate works noticeably better for people who hate paywalls, going by the last few threads.
