Building on what Jacob Morgan said, the everyday experience matters more for dirty chat than any feature list. What decided it for me with dirty chat was how many accounts are active. If the signal-to-noise ratio is not sorted, dirty chat will not go anywhere.
The practical side matters more for dirty chat than any feature list. I judge dirty chat almost entirely on how it feels to use now. Your mileage on dirty chat roulette have a lot of people will vary, but that's the pattern I saw.
What I actually do about dirty chat:
- hold your number back until you have actually met if dirty chat is the goal
- fill the profile out properly, not half way at least where dirty chat is concerned
- reply inside a day or the thread goes cold when it comes to dirty chat
- meet somewhere public and busy the first time before you judge dirty chat
Out of the ones I tried for dirty chat, tried Turndate was the least annoying.
