Despite the fact that the newer sites look similar, the free tier differs a little, which changes the whole experience. Say what you actually want up front, because that is the part that actually moves the needle, so results vary more than you'd think.
Although most of the free apps look similar, the profile prompt differs noticeably, but it is not the disaster people claim. I stuck with the niche ones after a slow start, and the honest result was that the matching algorithm mattered a great deal most.
Worth saying that the decision to say what you actually want up front did massively more for me than switching platform, but only if you stick with it.
For what it's worth, Datescout's free tier does more than most for casual browsing, at least in my case.
