The plan you sign up for just depends on what you will be using your internet for.  We suggest basic web browsing and watching Netflix, Hulu, Disney or other video services in SD (standard definition) on one device will be fine for a 5 Mbps Plan.  If you have more than one TV or device you will be watching video services from we recommend 10 Mbps Plan.  For those that play online games and want the highest resolution in HD on video services, we recommend the 15  or 25 Mbps Plan.
