It's worth noting what those percentages mean. They report percentages that mean that 1-n% of couples who use it as their sole birth control method for a year get pregnant. So 98% doesn't mean you get pregnant 1/50 times.
98% still isn't great (if you think about it, it means you're fairly likely to have 1 unwanted pregnancy in your life if you always use a 98% effective method), but it's a lot better than how it sounds to people who don't know what those percentages mean.
