I love using EQ. I especially like that I can import the fabrics. You can either scan in your fabric or there are a lot of manufacturers that provide EQ library files for each collection, like Moda and Connecting Threads. If I buy a FQ set or something I download the file for it and I can design with the actual fabrics.
Plus, Electric Quilt has fabric collections each month to download. I've gone back and downloaded years worth of them.
