Roughly my read too, with whether the interface gets in the way as the caveat.
My rule for dirty chat partners now is simple: check how quickly you can narrow a list down on day one.
Took me about 6 weeks on the app to work out that the real question was how much control you get over who sees you.
Where the room works it works fast; where it does not, what the verification step actually proves is usually the reason.
What separates the room from the rest of the field is whether the rules get applied evenly.
The thing that finally moved the needle on the room was being specific about whether the sorting can be trusted.
