I have EQ6 and it is not hard.
It is complicated, it does so many things.
It makes math and formalizing patterns very easy, once you learn the software ideas.
It is a very logical tool, once you walk through enough of the tutorial videos.
I use it to make printable patterns for blocks, to design complex borders, to test color/fabric combinations in blocks. Then apply those test blocks to a sample layout.
Even if you do not design a quilt with it and only use it to test color layout and placement, it is great!
Do not have a faint heart, jump in and practice, you will use it if you take the time to learn it.
