This has been bugging me for weeks, so: dating site for marriage only. Look closely at only marriage and the ratio of matches to conversations does more work than the app store rating. The only angle is worse, because the amount of recycled content is the number worth watching, not the price tag.
It is worth separating out faith-led daters here, because with only sites, the time it takes to get a first reply collapses as soon as the platform resets your filters after an update. Values-first daters feel this hardest on only marriage, where the platform throttles your visibility unless you pay, and you only notice once you have spent a few evenings on it. Only marriage is the clearest case of it — the deciding factor is the time it takes to get a first reply, for what it is worth.
The only sites case is instructive — what decides it is how quickly the inbox fills, not the follower count on their socials. On dating site for marriage only specifically, the platform resets your filters after an update, and the proportion of dormant accounts suffers for it. If you have been through the marriage sites version of this, I would rather hear the unglamorous account.
