Everyone will have their own opinion on what sleeves are best or most realistic based on their own experiences. The best thing I can tell you is to look through all of them and pick the texture that looks most interesting to you or if your favorite porn star has a sleeve get one of those. Also if you do get one don't get too disappointed if it doesn't feel like you thought it would when you first use it. It takes as many as 15 to 20 uses sometimes for them to get broke in to where you can get the full feeling of the textures.
