Anyone Switch from Hizentra to HyQvia?

I am trying to select an insurance plan for 2026. In the past it has been easy to go with the closest plan to the previous year from the same insurer, but this year is different because my current insurer has informed me that they aren't going to cover my Ig replacement medication, Hizentra, and suggested switching to HyQvia. My Immunologist is not keen on this idea because I have done well on Hizentra for many years. She also pointed out that HyQvia contains a lower concentration of IgG, implying that I would have to infuse more of it for the same result. But I have just read on the HyQvia website a claim that the hyaluronidase in it allows more IgG to be absorbed into the bloodstream, so I might not have to infuse more after all (not sure, because Hizentra has twice the concentration of IgG.) So I am wondering if any of you have switched from Hizentra to HyQvia and what that was like.

I do have the option to switch to another insurance company that covers Hizentra. It looks like the overall cost may even be less, but it's more or less an upstart company - in business 5 years and only 2 years in my state.
