I have had every version of EQ since it came it out. I am currently running 5 & 6 but fixing to transfer the files into 7 and sell off 5 & 6!
Eq5 & n6 are about the same. I prefer 5 but then I don't do machine emb.
EQ7 has now combined the best features of 5 & 6 and incorporated MORE emb/applique designs. It also has the unlimited # of times you can put on a computer! A HUGE plus!
I have taken a few classes through quilt university and found them to be a good resource!
I LOVE EQ for lots of reasons, but being able to design my quilts to use up the stash I have is the biggest plus!
