Things To Consider

Can you easily find out who owns the long-term-care facility, community, or business?

Beware of long-term-care owned by private equity or corporations.   You are going to be better off where there is someone at-the-top who is response-able and can be reached.  

Care at Home
Positives: You control who, what, when, and how things are done.  That is big!
Negatives:  If you are providing the care yourself, it can be exhausting, challenging, and sometimes even frightening. If others are providing care, you will need to screen them and cover for them during absences.

Care in a Facility
Positives:  The facility will do the "heavy lifting."  You will be free from the work yourself.
Negatives:  You will have virtually NO control over who, what, when and how things are done.  

Many facilities provide 24/7 staffing.  However that should not be equated with 24/7 care.  Whether you are your loved one is in assisted living or a nursing home, do not expect someone to check in more than every 2 or 3 hours - and it may not even be that frequently.   In memory support, you may find more attentiveness, but it will likely be in a group setting.  Some people have reported their loved ones in memory support are locked out of their rooms during most of the day. 

Under federal law applicable to nursing homes: 

"Quality of life is a fundamental principle that applies to all care and services provided to facility residents. Each resident must receive and the facility must provide the necessary care and services to attain or maintain the highest practicable physical, mental, and psychosocial well-being, consistent with the resident's comprehensive assessment and plan of care. "  42 CFR  § 483.24  

GOOD LUCK finding a nursing home where even 50% of a resident's physical well-being is met.

GOOD LUCK finding a nursing home where even 20% of a resident's mental and psychosocial well-being is met.

You can find various ratings of facilities online.   The Centers for Medicare and Medicaid Services (CMS) provide a star rating from 1 to 5.  From my vantage point, these are bogus.  CMS contracts with states to oversee, monitor, survey, and rate facilities.  Oversight and enforcement is horrible.  There is no other way to say it.  Sure, you may find some egregious facilities suspended or closed, but those are the egregious ones.  All the others that provide subpar care and neglect residents are left untouched.  

As for the ratings, they are relative and often politically influenced.  The long-term-care industry has a strong lobby.  A 5-star facility may be better than a 3-star facility, or not.  If it IS better, it is a matter of degree, or relativity.  It in no way means that facility comports to the extensive legal requirements for care.
