I don't know that anyone has experience with any other Z390 motherboard than what they own.
Best I can suggest is to read reviews.
You can also go to newegg and look at the feedback for a candidate.
Read them for any evidence of intrinsic problems.
The elite level motherboards will have superior sound, RGB lighting, LN2 capability, and sli capability.
All of which I do not value very much.
If you are interested on overclocking, I think asus and asrock seem to have the most active overclocking forums.
