My husband has been on Medicare for 6 years and me for 1. One thing to think about is the ability to go to your doctor or specialist ( without needing a referral) if that is important. So if you are used to going to a certain specialist you need to confirm they are in the plan's network if you opt for that.
Also not all doctors are even accepting new Medicare patients. If you are already established with someone, no problem, they will accept the insurance change probably,but we found when we moved to a different city that the Dr we wanted to go to was closed to new Medicare patients. So we went to another newer dr in the same practice. We like her but it was a disappointment at first.
So I guess it would depend on your plans for relocating and your current health ( need for specialists that you already know for continuing care).
If you have any other questions this is a great source of information from those of us " living it"
