Is home health care or a retirement community/assisted living facility a better choice for disabled seniors?

My two great aunts been living in their late mother’s house for years but now it is becoming too much for them.They need a landscaper and cleaning service to keep up with routine maintenance. But now one of them is going blind and the other has a hip problem. The family is trying to determine which would be better – a home health aide https://www.caring.com/articles/hiring-a-caregiver or a retirement community such as http://www.sunshineretirementliving.com where there are assisted living facilities. They have health insurance and some savings. The situation is getting worse and the family has to help them make a decision soon. Which choice do you think is better and why?
