This may just be in my area, but here are my observations:
OkCupid is more for people that are a little bit weird. The girls that have actually met me and even just gotten into conversations with, are usually a little different from mainstream society. They like a little bit of oddness in men. I'm hesitant to say hipster or nerdy, but that's about the only thing that comes to mind. I find that conversations are generally better on here because I'm a goofy individual and I like OKC's women a lot better than the other two, though sadly the userbase has tanked over the year and not many use it anymore where I'm at
Though there is the possibility that I'm a little bias as I did meet what I would consider to be my dream woman on there. Though I wasn't good enough to keep her... le sigh....
POF is more for women looking for a provider guy. Someone who looks good on paper. Interestingly enough, I did best on this when I was newer and not as good with women as I am now. Probably because I was largely naive at the time and was largely unaware of what I wanted besides dates and was easier to control. And I would consider the women are largely naive on there as well. I don't like POF as much as the other two, even if it has a larger user base. It seems to me that the users of POF are largely unaware of how the world works. I also absolutely hate how they moderate it. The women can say whatever they want, but if a guy sends anything with certain words/phrases on there the entire message gets deleted and you'll never know. Example: the word dirty is outlawed. The guy running it is a true chump. There's just no other way to put it. So you'll have to go largely indirect on here just to get your messages sent.
Tinder is the trendy thing and I do best on it now, though it's not my favorite of the 3. But the amount of people seems to have skyrocketed over the past year or so. It also helps that I'm fairly good looking and have learned how to photograph well after quite a bit of work on myself. The strategy you'll want to take with Tinder is have 3-5 good pictures of yourself.
--------A nice headshot, smiling (have tested this a lot. I get a ton more matches with a smiling picture than I do with anything else and I don't care what OKCupid's old data says. This is what my observations have told me)
--------Body shot of you actually doing something (example; I use a picture of me doing a flip into a lake)
--------Picture with an animal/friends
--------Random other shot that shows a little personality
Basically, you want to seem like a fun, good-looking guy on Tinder. The strategy that works with for me on Tinder is to open it and leave it for a few days before swiping on anything. Then start swiping and going through your conversations and after about a month you'll notice that you don't NEARLY as many matches as you used to. So once you've gone through the matches you do have and are sure you've gotten everything you can out of it, delete it and start over.
