All of these sites are great for finding all of your matches. And if you are thankful for them you can support them if you want to. but then comes actually finding someone lol. It doesn't matter if you look in the most popular or a single person management, it will be the same. Although every site has different people and gives new hopes. In the end though like I said it will be the same and it will be about you and the other person to be serious of what you want.
