Best Condoms?

My boyfriend and I recently started having sex. Neither of us have had much experience in the past, so we haven't tried a ton of different condoms. Currently we're using Durex Invisibles. They're fine, nothing fancy. We're both able to get off using these, but it's a little more difficult for him to get off than usual, and my orgasms aren't always as strong. They are perfect at their job, but we want to see what could possibly make our sex feel better.  We want to experiment with different condoms, but aren't sure where to start. Any suggestions on your favourites?
