Only used couple other dating sites (benaughty and citysex) so only have that ones to compare with. Very close, benaughty has a mobile app which I like, but hookuphangout probably wins (just) for having more girls and for being the only site (so far) which gotten me laid. Citysex was not bad too. Will report back by the end of the month.
My favourite sex search site is HookupHangout but CS isn't bad too. Much better than the couple of other sites which are basically the same. 3/5 from me, could hit 4/5 if I get laid at the weekend so might be back to edit the review soon!
