I don't pay any attention to the degree of difficulty labeled on the pattern. If I like it, I try it. Worse case scenario, you learn something new or waste a block of fabric. If you are to the point where you see an advanced pattern as looking fairly simple you are ready to take on any pattern you want to try. That's the fun of quilting, we are as knowledgeable as we think we are. Note: I wouldn't go buy all the fabric for a quilt that is labeled as challenging unless I had a teacher or a class to participate in, because those can be a bit beyond my current piecing skills. But, maybe not for you?
Edited to add: And if you get stumped, there is always someone on this Quilting Board that will offer help and guidance.
