The statement “Skype has a cooler name” isn’t actually so far off. Skype was the first major VoIP provider to explain the concept to customers in a practical way, and to make the service feel like a vision as opposed to a feature list.
Net2phone market in a business manner, citing reduced call costs, recording and conference calling as their main features, while Skype approach customers with the idea that they can call friends on the other side of the world for the same price as calling the guy at the end of their street (or for free if they have a computer with an Internet connection).
Skype win simply on branding and advertising, as they don’t just provide a service — they know how to talk to their customers. For more evidence, observe the difference in user experience on http://skype.com/ and http://www.net2phone.com/ . The homepage of the Net2phone website (after you get past an ugly and unnecessary country selector that makes you feel stupid for living anywhere but the US) barely even explains what VoIP is, or how it will be useful to you. “Consumers” is not a friendly word to have to big on your homepage, and Skype understand basic concepts like this.
