There's a few factors here. I think DMC Huron Valley, Henry Ford Wyandotte, and Oakwood South Shore are comparable. These are smaller, satellite, suburban community hospitals. They might be OK places to do a rotation or two when you want an easier month in a field that you're not interested in, but your experience will be limited IMO if you do all your training at one of these places. I did my internship at a hospital similar to these places, and we got very routine cases.
Sinai Grace is a historically Jewish urban hospital now affiliated with the DMC. It's definitely not as "nice" as the other three (uninsured patients, older fixtures/patient rooms, typical urban hospital, etc.), but it has a broader scope, more opportunities, and likely better training. It's located in a middle class, outer part of Detroit, which is generally free from the blight that you might see in other parts of Detroit.
Another factor you have to consider is location. The most desirable part of Detroit to live in for young people is just North of the city in Royal Oak/Ferndale. This is where a lot of the good restaurants, nice retail is, while still being accessible to downtown as well as Bloomfield Hills within 10-12 miles for commuters. If you live in Royal Oak (or perhaps more likely, just North of Royal Oak where the rents are more affordable), then you'll have an easy commute to both Sinai Grace and Huron Valley.
Henry Ford Wyandotte and Oakwood South Shore are both located in "downriver" Southern suburbs of Detroit. This is a less desirable part of town. Not really dangerous in any way, but just very blue collar, and out of the way from the nice retail that's in Oakland county.
I personally live in Dearborn myself which is a western suburb close to the downriver part of Detroit. I'm looking into moving towards Royal Oak for next year.
