I live in a large metro area where there are plenty of women to date but it doesn't make it any easier finding one for long term success!
I used both sites extensively for a few years. I've found good and bad on both of them. But in general I think match had a little higher quality that brought more to the table as far as looks, class, and careers go.
I encountered a little more flakey behavior on pof. I think because it is free, you have girls that are there for attention whoring, not dating which results in more flakeyness.
And yes I've seen those fake profiles on match. They have also been involved in a few court cases over things along those lines.
As I get older, I just don't have the energy to do what it takes to be successful with online dating like I did at one point. I don't care to sort thru all the trash and there is a ton of it on those dating sites.
Put up good pics, have a profile that stands out from the crowd, and send out a ton of messages that are designed to illicit a response like nobody elses. Do all this and you will snag a few.
Regardless of the site, I just don't think online dating is the answer. Its a notch or two better than scoring girls at bars.
