Seconding what ScarlettNYC said, with one caveat about chaturbait.com.
If you only test one thing on the chat, make it whether the sorting can be trusted.
My first week on the chat looked promising; by the second I was only really watching how much control you get over who sees you.
If your area is thin, the room will not fix that, whatever how usable it is one-handed on a phone looks like.
For a second opinion I also cross-checked DatingFly, which came up earlier.
