Others appreciate OkCupid's detailed questionnaire, which you can fill out in as much detail as you like. Want to screen out creationists, racists, or people who love One Direction? OkCupid lets you do that.
While you can't generalize accurately about millions of users, OkCupid has a reputation for attracting more folks between ages 25 and 45 who are interested in dating. Tinder users skew much younger and tend to assume people are open to just hooking up.
You can prefer one over the other—but, much like dating, online dating can be a shitshow no matter what app you use.
Superficial as Tinder may be, it does boast one huge advantage for women: Users can only contact other users if they've both indicated interest. In other words, guys can't talk to you unless you've given the green light. Since women who date online tend to receive tons of unsolicited messages (many of which are unwanted and downright creepy), lots of ladies prefer the Tinder model. Superficial > stalkers.
But OkCupid's questionnaire does allow users to be clear about who they are and what they're looking for, and even screen out qualities they want to avoid. Don't want to end up on a date with Satanists/diaper fetishists/Trump supporters? OkCupid lets you screen for that.
