Most successful online dating site?

Title says it all. I'm wondering what dating apps people have found to be successful. I've tried POF, found a lot more bots and fakes over real people, although i have made a few friends off of it. I've tried OKC, didn't have much luck on that. I'm not looking to dish out money (eharmony) in order to have no one message me, and I'm not looking to sleep around (Tinder). I'm merely looking for a potential long term relationship. I just want to put myself out there in hopes that I might potentially find my weirdo. Any help is appreciated.
