Experience with Donanemab and Lecanemab

My wife has been diagnosed with Alzheimer’s and her Mayo neurologist recommended treatment with either Donanemab or Lecanemab. Does anyone have any experience with either of these drugs? It seems like we have a million questions.
How do you choose between the two?
The infusion time with either one is relatively short, but sounds like your actual time is much longer. Are you generally able to get by with one day of medical each cycle?
How bad are the side effects? Are you potentially losing 18 months of relatively good time during the disease progression while you go through treatment?
There are numerous articles which question whether the benefits from the clinical trial will actually follow in actual practice. What kind of actual experience have people experienced?
I am not sure why our family and myself seem to be questioning this treatment. My wife is a three time ovarian cancer survivor. She has obviously been through quite a great deal from a medical standpoint. The medical community and specifically Mayo has saved her. If one of these treatments will help there is no question we will proceed. I am sure part of our hesitation is in our situation the treatment cannot be done at Mayo.
