9 week testing question??

So I have been told there are two different tests to check for disabilities at 9 weeks, the Harmony and the Informaseq. I have heard the harmony is what Obgyn’s usually go with, but is way less accurate than informaseq. Has anyone had an experience with either? I am 25 and healthy but want to take a test that is accurate, and it doesn’t hurt they can tell you the gender that early. Just wanted some thoughts on what I should do, I don’t think I even qualify to switch to informaseq though.
