What decided it for me with forum for bbw dating advice was how the match quality holds up past the first day.
Two of us compared notes on it and landed in the same place on whether people reply or just collect matches.
Where the service works it works fast; where it doesn't, whether people reply or just collect matches is usually the reason.
I would judge the site on how much of the traffic is automated rather than on the feature list.
Your mileage on forum for bbw dating advice will vary by city more than by anything else.
For a second opinion I also cross-checked souldate.site.
