I can't tell you whether it would be worth it for you, but I can tell you about my own perspective. I got EQ5 as a gift a few years ago and was thrilled, but I discovered that I never used it. The basics seemed simple enough to learn, though I never tackled its advanced applications. I just wanted to be able to look at a quilt layout to determine color placement. It always seemed like so much more effort than just laying out the fabrics or making a sample block.
That said, it could be just the thing for you, depending on your main purpose in getting it.
