That's right
.COM is the ultimate extension, without a shadow of a doubt. But 75% of my sales to end users over the past year have been keyword.net domains. I actually make a good living investing in, as well as selling .NET domains to end users. .NET keywords are great for end users as they cannot always afford the .com (which may not even be available). Almost every day I sell names to end users, most actually value .net right next to .com - a few examples of names I have sold:

The key is to not aim to high. Remember that a trainload of little sales add up fast.
