Same as Jesse, with one difference. what decided it for me with dating sites were whether the effort pays off.
Two people can have opposite results with dating sites purely because of how it handles day to day. Once I stopped worrying about what people get out of it, dating sites got a lot simpler. My experience with dating sites shifted completely once I paid attention to the bot problem.
Most of the frustration with dating sites traces back to how real the profiles are.
That is what worked for me on dating sites for men who are tired of the swiping culture; others here disagree.
Rendate lately came up in another dating sites thread here and it was decent.
