Condom help??

Brooks
What is the safest condom or one that is the most reliable or least likely to break? I'm not sure if I'm allergic to latex or not but I do have sensitive skin. I've heard that the skyn ones don't have latex but are more breakable and don't prevent against stds or something? Also mixed reviews on Trojan and durex? Do they all have lube and spermicide? Should they? Hah I have no idea thanks.
