=_= shows how much you know.
Yes because Cleveland is so small. A total of 190 students a year (160 from Case, 30 from CCLCM) really needs to fight over spots in 4 hospitals (Clinic, UH, Metro, VA).
Doesn't NY have 8 medical schools?
Back to the OP's question: yes, Sinai is in a much better location and I think you'll have more fun there. Life is quite expensive in NY, but after saving 10K a year I think you'll be able to afford to spend some. With that said, I think Case has a more relaxed curriculum, more opportunities for research, and less competition for attention and rotation.
In 2008, Sinai actually had more NIH funding than Case (I believe Case's total includes CCLCM, but I could be mistaken) : see

I would argue that student research opportunities at the two schools are comparable, but focused on different areas. Sinai's research strengths are in Geriatrics, Psychiatry, Neuroscience/Neurology, IM (particularly GI, Cards), Rehab, ENT, Global Health, and Health Disparities.
Sinai also has a relatively relaxed curriculum--almost all exams and quizzes are online, can be taken anywhere with internet access, and are usually open from Thursday - Sunday. Few lectures are mandatory, most are videotaped, and 1st year classes usually start at 10 am, Fridays rarely have anything scheduled past noon during 1st year.
Sinai is located between the UES and East Harlem, offering exposure to two very different populations. It is ~20 mins to get downtown on the subway (much better than Columbia or Einstein). On campus housing is very affordable <$600 for singles and I can get from my door to the classroom in 5 minutes at most. Central Park is also less than 5 minutes away, with the Guggenheim and the Met within walking distance.
But I would have to agree that Case's facilities and affiliated clinical sites are superior to Sinai's affiliated programs. Case also has a better national reputation, although Sinai has a strong reputation on the East coast. Your experience will be very different depending on which school you choose--Sinai is a very unique program due to the HuMed program, its location, its culture, etc. Case also has many strengths. Good luck!
