But in all seriousness, most birth control have the same percentage for effectiveness. The main variance is actually the person. For pills, some people forget to take them and then they're not as effective, for the patch, they can sometimes come off without the person noticing, condoms can break or puncture or be defective, etc.
If you're wanting to have sex, find the type of birth control that's you'd be most comfertable with, though I would recommend away from injections due to the increased chance of blood clots. Also, if you really want to make sure, then use a condom as well as the birth control. [ Ice232's advice column | Ask Ice232 A Question ]
