If it's Electric Quilt software you mean, I can say that I have found EQ7 to have a steep learning curve. Some people take to it like a duck to water. Me, not so much. As far as I can tell from previous threads on this topic, creative and artistic people seem to find it intuitive. Programmer types, such as myself, do not find it intuitive at all. In my opinion, a downside to EQ is that it is quite expensive -- not just the software itself, but also any classes people might want to take online to learn to use it more effectively.
I do find EQ7 useful, especially for quickly changing the sizing or coloring of a quilt, and I have gotten to the point where I can design simple quilts and borders with it. However, it took me a long time to get that far.
