Broadly speaking, the ones with a paywall have got noticeably worse for bots, so results vary more than you'd think. The pattern I keep seeing is that the distance radius matters considerably more than the matching algorithm, though it depends heavily on where you live.
To be fair, I'd read the last few pages of a thread before asking rather than test two platforms at once, since the difference in reply rate is obvious. From what I've seen, I'd test two platforms at once rather than widen the distance radius early on, since most complaints trace back to that one thing.
Over the last month I noticed the reporting system behaving differently on apps with a strict photo policy, but only if you stick with it.
